Just heard from WGT that Their QA team is looking into my problem. I'll also try my son's computer and phone when he gets home from work since it doesn't work on my devices.
WGT QA team has fixed the problem! There was a piece missing from the iron set causing it to not be able to be equipped. The desired iron set is now equipped and able to be used. Thank you WGT for your time and trouble.
Good to hear you got it resolved Mr Tee, perseverence wins the day. : )
