Table Collection Custom Actions Source

Hey guys help need.

I noticed something strange in my GlideApp today. I cannot select the actions which are related to the collection (table) data source. I want to use an action as item click action but I can select only the action which are linked to the tab source table.

Worth mentioning here is that i am using different source as my tab source and my collection source is a different. In past i always had the same structure and i could select the action which are linked to collection source not the tab source.
Is it something glide changed? Or am i doing any mistake here.

For reference please see the video attached.

I believe this is a bug, and has been escalated to Glide.
