tldr; It wasn't that (details below) but for simplicity sake I'll simply say, IT'S FIXED! Steps:
Uninstalled Islander v1.0.1
Made sure the entire aircraft folder was deleted
Re-installed Islander v1.0.1
Downloaded the AFM G5 Islander patch from here.
Installed the patch per the instructions on their site.
Started a new flight using the BN-2B-26 Islander G5
Registered the aircraft
Tested the G5. Looks great! See attached image.
@airwar THANK YOU for all your help! It is much appreciated.
