This is usually caused by some corruption in your Custom format list. If you could send me the file I will try to fix it for you
John, I took your lead and cleared some strange custom formats. It now looks OK.
I do not see an Accept button?
If I have any addition problems I will get back to you.
Great! Glad you manged to find the culprits in the list (if you want I can show you what you need to look for)
Thanks for offering to accept (you will find the Accept button with this message)
