Component not updating when library published.

Sorry, I’m new to using external libraries so forgive me if I’m missing something. So I’m in one file with components. I tried to find the answer in the forums, but failed. I’m sure it’s in there somewhere, but there’s lots of publishing posts.

I have a component in this library that doesn’t seem to want to update properly in a different file. When I click on it, its properties are out of date. If I select “go to master component”, it goes to the correct component in a different file.

I don’t know if this is relevant: I see under the little book icon, that there are 66 changes in the file. I don’t actually see the problematic component there. I see a bunch of old components I haven’t touched in ages.
So I hit “Publish” anyway.

So after a couple minutes of chewing, I see a message at the bottom of the screen. “Successfully published library updates”.

I see there’s still a blue dot on the book icon. I click it. It still tells me there are 66 changes in the file.
