@Yrstruly2021 So, in general, avoid bi-directional relationships and try to avoid many-to-many relationships. Your Country Codes need to be cleaned up. The *-* relationship is being caused from what I can see by a few blank rows in your Country Codes table. Clean those up in Power Query. Probably then use that as a bridge table between your Users table and your Paid user count by country... and User county by country. I would also collapse those two tables into a single table. You also need to clean up your Users table. There should only be one row per User in that kind of dimension table. Again, I think this is caused by blank IDs. That should be a start. Hard to really go much deeper until that is all cleaned up.
