Greyed out when post type slug has a dash

Hi Rachel et al,

I just wondered if you could point me to where in the code I could go to fix the issue where if the custom post type slug contains a hyphen, the ability to assign them is lost as they are all greyed out? I know this issue has been raised before (https://www.ads-software.com/support/topic/greyed-out-taxonomy/) and there was mention of a fix coming but I’m on the latest version and it’s still there.

Thanks.
