CC5.06 changing sub division clears 'currently used' sliders

Hi there.

Something I encountered for the first time yesterday, when I change the sub-division level of a character, it clears all of the ‘currently used’ morph sliders in the modify panel. This happens on all characters. If I save the character without notiicing, I lose access to the ‘currently used’ info permanently.

I often leave everything available on the modify sliders there so that I can see what I’ve changed on a character.

I’ve been using 5.06 for a while now and this only started yesterday, so I’m guessing it’s an issue I need to fix locally.

Is there a way to clear preferences (like in Photoshop), or is it best to resinstall and hope the issue doesn’t come back?

UPDATE: It seems to only have affected a few characters. Maybe during one session there was a bug (possibly following a crash or force quit) – so when I saved the work over the last few days it has led to this issue on everything I was working on. Previous characters I was working on seem OK (i.e. I can change the sub-d level without an issue).

Many thanks.
