App & Data source items not deleting

Hi There
Extremely untalented user but have got a long way into an app build successfully so far.
I have a Team screen like the YouTube examples (with no photos) and it all works fine. I can add new team members and Edit, however I have set up the Delete exactly per the YouTube Delete Data from a Data Source - I have a Delete button appearing on a right swipe but nothing happens in App or Data Source file (Google Sheets) when the button is clicked on my Android device. Testing on Web does not function as the right swipe returns instantly before the Delete button can be clicked.
Any ideas any one??
Cheers

Please review How to ask Great Questions v2.0. It’s important to include screenshots of your blocks and/or a link to your project. We can’t see how you’ve set things up so we have no idea how to help you without that.

Apologies - the screenshot is uploaded now.
