Hi Skeeter,
I took the time to recreate your match in exactly the same manner, including the 2up going into #7 and the birdie/par result. Unfortunately, I could not get the dormie message to be displayed incorrectly.
We've had a few scattered reports for this, so the next time you see this happen please take a screenshot when the message is on the screen in error and then submit an in-game bug report immediately after you take the screenshot. To submit an in-game bug report just right-click anywhere in the game client and choose the "Submit this problem to WGT" option. Bug reports submitted in this fashion have a lot of extra information included with the report so it may be helpful in tracking down the cause of the erroneous message. =)
Thanks
