CATIA Material Revision issue Appearance

Hello, I have an issue which appeared when updating to the new FD01-version this weekend. All of my materials have automatically gained a revision (A.1) in the title. This revision name can not be removed. For example, a basic steel alloy, S355J2, now appear as S355J2 A.1 in the BOM-list on a drawing. This is misleading and causes confusion for a steel contractor who receives the drawing. Does anyone have a solution for this issue?

I unfortunately have to update 100 + drawings manually for my delivery...

Best regards, 

William
