Pictures in Media Library

Initially Picu was uploading collections to wp-content/uploads/picu/collections/#### folders and at some point uploads for new collections go to media library and not to the wp-content/uploads/picu/collections/#### path.

I cannot track what changes were made to the site since it was working.

Here is the infor from picu/settings/debug:
