Hello Jimmi,
I am a bit confused with the screen captures you provided. It looks like you are using FLRIG and at the same time telling WSJT-S to control the 7300. If you are using FLRIG as your radio controller then you should select FLRIG in WSJT-S.
Maybe I misunderstand your screen shots, but if you activate FLRIG and then try to tell WSJT-X to control the IC-7300 instead of FLRIG, I could see where you might have a hamlib problem.
Regards,
Jim
