First I am not anything to do with EasyProfile but I had a similar thing that I wanted to change.
I added a language override where the words "No information entered" were entered and changed it to my needs. There you can add what ever you want instead of the default.
How to by numbers associated on the screen crabs.
1. Extensions > Language Manager.
2. Click Overrides
3. Add New
4. Searcher the term you want to change
5. Make sure COM_USERS_PROFILE_VALUE_NOT_FOUND has the front end lower case i and e. and click it.
6. Change the default text here to 0 or delete completely.
7. Save
