I am experiencing the following issue. Currently i have configured the plugin to display only in K2 items in INLINE and FLY IN. Whenever i try to add, for example display in Article, i everything in the tab disappears. When i try to include only some articles not in K2 it disappears again.
When i disable the INLINE and FLY IN I am able to add Articles in "Display In Components". I ask for some ideas about where the issue could be.
