As of 2.53 Release 2, View->Show Types and View->Show CSets in the ZQuest Editor work in a buggy manner when viewing certain screens.
What happens is the following on these affected screens.
The View->Show Types and View->Show CSets options only display their respective metadata parameters on combos on the screens adjacent in the main panel. However, if you enable View->Show Flags to show combo flags while either option is active, then their respective metadata gets displayed like it would normally.
Screenshots to display this issue:
View->Show Types and View->Show CSets are active, respectively.
View->Show Flags is active and also View->Show Types and View->Show CSets are active, respectively.
