Attachment for Content Articles plugin Incompatibility

Thanks for the awesome support! (sorry, I'm a novice!)
FIXED! The editor problem was fixed with JCE for FlexiContent! Thank you!

However, I still can't get my attachment button to appear in my FlexiContent Item editor. I included it in Fields/Description -> "specific plugins only" but it still didn't work.

Do you recommend any compatible attachment plugins that can be searchable from the front end?

Thx again
Greg
