I would like to report a bug in your K2 component. In the category list, after I delete, it still shows up in the menu / category selection. I cleared the cache but it doesn't seem to help. As a matter of fact, I deleted two category list and they both show up in the menu/category selection list.

They are Trashed - so you can restore them if nesessary or you can clear trash to delete them permanently

Thanks for your response but I'm not sure what you mean. Trash is emptied right away as soon as a selection is made then click on the trash icon.
