PowerBuilder 2022 R3 Build 3356

We are using a PowerBuilder application to call a Blazor application to do some Fee calculation. With some users, the browser shows the currency symbol of a pound sign instead of a dollar and the drop down date function is in French. If the same Blazor application is called by Edge separate from PowerBuilder, all is correct with English and Dollar signs. 

Presumably there is a locality setting somewhere but I can't find it.

Assistance appreciated.
