Issue with variables and pages

Hey there!

I'm having a strange issue with variables and pages.

Scenario:

1. I have several libraries (A/B/C/D)
2. I have a file with several pages (Cover/Research/Wireframes/Design/Prototype/Archive)
3. Only Library A is added to this file.
4. On the "Design" page, it's showing me variables from library B - why?

What helped?

1. Duplicating the "Design" page 😲
2. It no longer shows variables from the other library.

Additionally, how do you deal with the old text styles or hidden components from other libraries?

Thanks!
