After a while of using Tasker and accumulating many Profiles - most folks end up with a mix of user-named Profiles along with Tasker-named (which are un-named) Profiles.
Those un-named Profiles don't show up in %PENABLED or %PACTIVE and cause a bunch of other issues.
There should be an option to indicate un-named Profiles when viewing the list in the Profiles Tab.
After discussing in a thread on reddit the most popular (and simple) option idea was to put Tasker-named Profiles in italics in the Profiles List.
Doing so could of course be an option in Preferences.
