Identical - Thanks @merefield

Sure enough, I ran the query you shared in your other post and saw a few duplicated [data explorer](https://meta.discourse.org/t/32566?silent=true) queries.

I took the plunge and I did as you did, DELETEing the higher ID numbered ones, keeping the lower numbered ones in place.

Added the [Data Explorer](https://meta.discourse.org/t/32566?silent=true) plugin back to my app.yml and it rebuilt perfectly with no issues or errors.

Thanks again 🙇‍♂️
