Reporting currency question

 Hello all,

I'm a little stuck at the moment. I'm rather new to reporting and seem to have come up against a little issue.

I'm trying to report a currency amount in one of my reports (Highlight), the input costs are all GPB, however, when the report runs it only shows me the sum in USD. I can not see anywhere to change this option and unfortunately, Clarizen support can't help me with this request.

Any guidance on how I can amend these settings is greatly appreciated.
