Error copying Propales, invoices


Using Dolibarr 14.0.3. I checked the Demo versión and when willing to copy for example a propale, in the popup window a dropdown selector appears.

That is my problem. In my installation doesn´t work. The dropdown selector does not appear.Tried to clear both server and chrome cache, but still same problem. I have this problem since I updated from 13.0.4.

Any suggesitons? Thanks!
