K2 v2.6.6
Joomla! 2.5.9

Recently upgraded to K2 v2.6.6.
Now, unable to Inherit parameter options from category, in particular hide extra fields. Was working fine prior to updating to K2 v2.6.6.

I have tried to hide extra fields at the item level (item and category display) and when Inheriting parameter options from category.

Any help would be appreciated.

Hello Lyle,

Clear your cache both Joomla! cache and browser cache, then if there is no change backup and then reinstall K2
