I've clicked on the green Buy All button, selected Anywhere, and then Auto-select,
and on the pop-up I've cleared the checkbox, and then clicked Start.
On the new Buy Wanted Lists page, I can see that four stores are shown. However,
I'm also told "244/254 assigned (96%)".
When I change Wanted Lists to Wanted Items, I can see four items listed:
34337 Wheel 8mm D. x 6mm with Slot - Light Bluish Grey - Qty 3
11477 Slope, Curved 2 x 1 x 2/3 - Medium Nougat - Qty 3
970 Hips - Light Nougat - Qty 2
3626pb3247 - Minifigure, Head Dual Sided Female Dark Brown Eyebrows, Nougat Lips
and Freckles, Sleeping / Smile Pattern - Qty 2
My wanted list asks for 12 x 34337 and 4 x 11477, and the proposed orders already
show 9 x 34337 and 1 x 11477.
What I don't understand is why these pieces are missing. When I search each
item on BrickLink, I'm told clearly that there are plenty of lots, in the
desired colours, available to me here in Australia, and, with the exception of
the hips, from many stores. On Buy Wanted Lists I have two Exclude filters: Disliked
stores (of which I have only three) and Stores that do not ship to me. Given
that each individual part page shows stores which DO ship to me, I must presume
that this should not be a factor.
Can anyone tell me why Buy All does not completely populate my proposed shopping
carts, and what I can do to fix this issue?

Can anyone tell me why Buy All does not completely populate my proposed shopping

Do you tick the checkbox “Select stores when item price is lower than store Minimum
Buy” when you start Auto-select?
and what I can do to fix this issue?
Try other options, like limiting to Australia, or requiring. Sometimes, having
more constraints helps the algorithm.
You can also try to deselect a few items in Wanted Items (the most common ones
or the rarest ones) to do the selection in two batches, or select one store manually….

Firstly, thank you for replying.
As I wrote in my post, I've cleared the “Select stores when item price is
lower than store Minimum Buy” checkbox, as there seems little point in proposing
a cart that the vendor won't fulfil. However, just looking at the first item
I've listed, 34337 Wheel, for example, if I select the first listed vendor
of new pieces who'll ship to Australia (they're currently offering 15
of this part) I can create a cart with just the three pieces I want, and the
store makes no mention of a minimum buy when I go to the checkout.
For three of these items, I can find a vendor who will ship to Australia with
no minimum buy. I'm at a loss to understand why the store's algorithm
would exclude them.

Seems I forgot reading that after I reached the end of your post 😅

But the algorithm has then more sellers to choose from and can use multiple sellers
to fulfill a lot that none can fulfill alone.

The algorithm can’t check all the possibilities in a reasonable time. So it
cuts corners… or whole patches of the solution space.
And some decisions seem stupid to us… but not to the algorithm, because we don’t
view the problem the same way.
That’s why changing a small thing (add/remove an item…) can nudge the algorithm
to a different decision that changes its results completely… or not.
Giving it more sellers sometimes helps because it releases a constraint… and
sometimes it hinders because the solution space is bigger and is cut down the
wrong way.
