I see 40 notices on the "My Preferences" page in the "advanced" theme. There are 3 notices per each field displayed on the page and they look like this:

- define these missing fields in "user-profile" unit unit config
- fix the used "Selected" tag to work with fields where only 1 option can be selected (regular checkbox fields).
