borisv do you belong to the plugin support?
Just for the record, i ended up finding the issue wich was more a conflit of options.
If this ever happen to someone check the “Profile Form” and see if the “Field(s) to show in user meta” section dont have “Biography” selected.
This was the reason that i was getting biography double, at first i tought i was drunk but on the next day it was still doubled.
