Word jump or recent doc list on right click keeps coming back

For some reason, no matter how many times i remove some items from recently accessed files (right click Word icon on taskbar), they keep coming back.

Thank you bro67 for your input.
Must be a 1903 update issue.
Never had to do anything before except remove them one by one and pin the ones i wanted to keep.
Anyway, did go to settings as per your good tip, and set it to keep 5 most recent but nothing has changed.
The minute i close Word and re-open, 10 recent re-appear again.

Zero has improved things but i'm still getting two recent (other than the pinned one).
Should i tweak something else?

Just FYI, this is happening to me also. Even more confusing is that after clearing 'unpinned documents', the document names are still there. There is no right click 'Remove from list' command anymore. And, even after 'clearing unpinned documents' the list is still there, and an attempt to left click gives "The item you selected is unavailable. It might have been move, renamed, or removed. Do you want to remove it from the list?" Clicking on Delete removes it temporarily, and you can go through the list and delete them all, but after opening one new document, the entire previously deleted list reappears, and not selectable. Only the Office documents are affected like this; other taskbar items behave as they used to. It does seem as if 1903 has messed up the Office jump lists.

"I changed both settings for files and folders to 0 in Word and Excel and..." getting only 2 unwanted on Word and a whole bunch on Excel.

-never had this issue before 1903 update, in fact, never had to worry about any of it at all!

At least it's not doing it on LibreOffice... oh, oh!
