Library Updates Not Recognized for Publishing

I have a robust design system that I have been making updates to (multiple times a day) over the last week. Today I noticed that the edits I was making were not being recognized when I went to “Publish Selected Components”. Literally, none of the changes I am making are showing up and the Publish button is disabled.

Any ideas on what the issue might be? Obviously, if my changes aren’t being published and propagated, there’s not much point in having a design system as a separate library.

Have you tried fixing invalid components before publishing updates?

That seemed to do the trick. Thanks for the help. That had not prevented me from publishing in the past. I appreciate the guidance!
