Problem with section separator and textarea placeholder

[CastingNorge]

Hello,
I have several problems with the plugin, firstly when I specify placeholder text for the Textarea field then nothing is displayed on the registration/edit forms. How to fix this ?

Another problem is with the separator section, when I add new section to the user form, then I receive PHP notice on the frontend, which specifies that the ‘colapsed’ index isn’t defined in /userpro/functions/fields-functions.php file on line 250. How to correct this ?
Regards
