average on a calculated column

I am trying to do an average on a calculated column (Snapshot of the calculated column is below). It calculates

correctly when shown in a table on a row level. 

However, it shows infinity when I want to do a card visual using the same column (Snap below).  That avergage should change when adjusting filters. It has always worked for my other cards but the issue may be the calculated column? Any workaround?
