Those all seam to be alternate numbers. If you use the search bar on the top
and enter them individually you can find the main number so perhaps use that
number instead

You can try to import the XML file to the program BrickStore 2022, it tries to
fix those errors automatically, then save as BrickLink XML and then you can upload
it here.

You are using the alternate numbers. Bricklink does only recognize those numbers
when you search manually, not when you put them in the URL or when you import
them. That's really something that Bricklink should fix.
LEGO assigns a new number for every (minor) mold change. Bricklink only follows
if it is a functionally relevant or visually distinctive change. Thus more and
more parts get alternate numbers assigned.
