Moza R5 not working with PC

Very new at Gaming.  Purchased a Logitech G923 for my PC and out the box it worked, purchased a Moza R5 installed pit house and cannot get wheel to work with F1-25.  Have sinked Moza with EA and Steam and still can't play the game.  Controls on the Wheel are inoperable, can't move left/right or up/down/ the  Y,A,B,X controls don't function as they should (B, diffidently is not Back).  suggestion>
