Position mapping problem in ABDCE

Hi

ABD CE ver 10.01.00.36

We seem to have a problem in our office with the Position Mapping.

Some of the icons don't get numbers, typically the first 2 which make the whole thing broken.

Any ideas?

I've tried different setting in Preferences such as

"Use Position Mapping" on/off

Ribbon->"Auto-Generate KeyTips" on/off

Also tried regenerating new .upf

No difference.

Thanks in advance
