Problem with custom upload path and files in custom fields

Hi! I’ve temporary set (for couple of minutes) “use custom upload path” in file option. After then I’ve removed it and go to default settings (remove from field and disabled this option) then save the page. But the problem is there option can’t save it. The files still uploads to this custom upload path and I haven’t option to go back with default wp-content folder.

Additionally I’ve use this form without any problems but after you released version with this 3.1.4 " [Pro Forms] File Uploads – Improved security by double checking for MIME type" my files aren’t uploads correctly into jet engine custom fields.
