i assume you mean TGC2 this is the TGC1 forum,It happens when another tee maybe the Red Tee is close to the green on the Hole before.You have say Pin 2 hole 8 on hole 9 etc.All you need to do is delete the hole,place the Pins first,then just add the tees later.Just save before you alter the course just in case..
bit like this problem at lytham as you can see,says hole 17 pin 3 but its the flag on hole 16 hope it helps,if not just send a message
just delete hole or holes were problem is,create new holes,place 2 pins,then the new tees then just re-number hole in hole setting.

It was suppose to be patched in TGC2,but we all know how problems with a patch and HB turned out.
