Why does my "Contains" tab for a part have drawings in it?

All of my basic standard library parts - in the "Contains" tab, they're showing a lot of drawings in a blue font. Can anyone tell me:

1- What the font being blue means?

2- Why are drawings showing as being contained in a part?

It's a major problem because any time I try to move a state on an assembly containing any library part, it tries to move thousands of different files all linked through the library parts. Many aren't in the correct state to be moved, so it just throws an error, which is a minor annoyance. Sometimes, however, the files are in the right state and we're moving multiple projects through workflows when they shouldn't be moved all because they both reference the same standard part.
