Has anyone have his libraries dissapear from the dependencies after regenerating the viewpoint? [Pending]

Has anyone encountered a case where his recently added libraries would directly dissapear whenever he regenerated his viewpoint?

Afterwards, I tried adding the plugins directly to the plugins folder, and restarted Capella Studio, same thing happened after regenerating the viewpoint → The libraries dissapeared from the path build.

Edit: To be clearer, the issue is adding new libraries that dissapear as soon as the viewpoint is generated again. Whereas previousely added libraries were not touched.

No one had ever seen his dependencies DISSAPEAR after regenerating the viewpoint?
