Hi, Jousef!
Could You please say where I can find “Add selection from viewer” button. I use Firefox and Opera but in both cases I can’t found this button.
Best regards
Yury
Hi @yyatsuk!
First of all sorry for the late response - opened your post but forgot to answer 
Did you resolve that in the meantime? Let me check it and get back to you!

Hi @yyatsuk!
Delete the mesh results and then you are able to assign everything. Thanks to @rszoeke by the way , thought it was a bug at first sight.
Let me know if you have any further questions.
Best,
Jousef
Thank You!
Best regards,
Yury
