25R2 Generic Inquiry Redirect not working

Hello all

  I’m upgrading our product to 25r2 and find that this code that redirects to a GI named ISPSAllocationWHOrderSOLineSplits&SOOrderNbr has an issue.  In 25r1 this forwarded to a GenericInquiry.aspx  and now it’s GenericInquiry.html.  The ‘Slot A’ text makes me think that the Modern UI might not be working correctly

string inqName = $"ISPSAllocationWHOrderSOLineSplits&SOOrderNbr={WHOrderToRedirectTo.OrderNbr}&SOOrderType={WHOrderToRedirectTo.OrderType}&WHOrderNbr={WHOrderToRedirectTo.WHOrderNbr}";

throw new PXRedirectToGIRequiredException(inqName, PXBaseRedirectException.WindowMode.New, true);

sends me to a GI page that doesn’t seem to work correctly
