Thank you for the follow up on this. I thought by clicking on the Apply button after each new bit entry was sufficient to add a new bit (which you mentioned you did).
I didn't realize (or maybe I forgot) that the OK button had to be clicked after each individual entry to "lock it in". Like you, I probably would have added a bit, clicked Apply, add the next one, etc., then clicked OK when they were all done.
So, thank you again for the follow up!
P.S. - I always run everything As Administrator. Avoids all kinds of road blocks.
