HY jsprogg thanks for your cooperation.

Funny thing. I tried what you said and... it's all unchecked. The numbers appears but the option says not to.

So what I did was select the Affect All in the top of the Custom Polygon Display options window. Then I check all show numbers option boxes (vertices, faces, uv's, edges).
Hit apply.
Wait for the command to be completed.
Now I uncheck all the show numbers and hit apply and close.
After a while (big scene) the numbers are gone !

Well, that was odd but worked this way.

Thanks again for the cooperation.
