Dedupe based on customer field

I have a report that shows remaining story points per person.

the row(s) are assignee and the column is story points. There is a dimension in place as I need to select multiple customers and exclude others.

the issue is that 1 issue is being counted multiple times as we have a custom field called “customer”. This is a multi select … if you select 1 customer you get the right point value … if you select multiples it multiplies. I need to only bring in the story points once. i.e. where I expect “Developer A has 8 story points” I instead get Developer A has 64 story points.

I’m guessing its a custom formula on the page dimension

Anyone from eazyBI have any thoughts on this please?
