In the Character panel often it is not possible to change a font weight from Regular to Bold for example. I have to go in the font menu and select the font specifically.

Also, in the character panel the menu to change weights does not change anymore when I select a different font. For example: Metropilis Black becomes Calibri Black (which does not exist).

Clearing caches and trashing preferences does not help.
