Publishing Library after changing one component : dozens of other unrelated components marked as "modifed"

I’m the only one with edit access on that file, I’m modifying a published component in a simple way (change bg color on one of variants for example).

I go to “Publish” and Figma detects dozens of other components of the same library that have supposedly been modified and are flagged as such. Those components don’t contain my modified component as a child, and are totally unrelated.

This happens several times per week.

What could this be ?

Figma doesn’t show what properties or how the components change in any way, and I don’t find any API methods to create a plugin that would show this information (differences between published version and current version).

Does anyone have any clue about this please ?
