Trnasport Window In Dorico 2.1

Hello I’ve recently reset my computer and reinstalled Dorico 2.1 everything works amazing except there seems to be a little glitch with my Transport window. The green marker that shows where you are within the piece moves way too fast and is constantly ahead of actual playback. Also when I push play the green marker must move some four measures before it begins to play sound!!! Any insight on how to fix this. I’ve already reinstalled the program again to no avail.
Thanks guys!!!

Could you please go to Edit > Device Setup and in there change the sample rate to some other value, wait a few seconds and then switch back to the old rate. Close the window and try again, still same behaviour?

Thanks so much
