WooCommerce Reporting USD sales in UK Pounds

Dear Sir, Madam,

We have your plugin running on our website: energydots.com

All UK transactions are showing correctly in WooCommerce Analytics.

But USA transactions are showing as Pound value. e.g. $36.00 is showing in Analytics as £36.00

Do you have a solution to fix this problem?

I have attached an example order and example analytic report.

Thanks
