Fiori Employee Lookup search is case sensitive!

Hi

I have the following components installed for Employee lookup and when running a search on first name, it's case sensitive!.  Does anyone know of the fix for this bug?

When I was running UIHR001 100 sp3 it only allowed you to search on surname, so I guess sp4 is a slight improvement!!

UIHR001     100 sp4

GBX01HR5 605 sp3

Thanks
