Visual Filter error dues to inactive relationship

Hi Guys!

I have this measure that uses two different tables: [THA] comes form table [robotic data] and [primary hips] comes from [total sales by year] table. They both have column [region name], however that connection is inactive and I can't seem to activate it. I tried using USERELATIONSHIP function inside this measure to make the connection active but it didn't work, because the measure is not filtering on any regions. However, I need to add Regions as a filter on a visual and that's where the problem is becuase it's not calculating correctly becuase of that inactive connection. Please help!
