This site is still a work in progress.
This is due to selecting a ped model.
You either have to deal with this or put in a request on the forum for your ped data resetting or if you don’t have the patience to wait for the request, create a new character with a similar name (as you can’t have 2 characters with the exact same name) and then use a “freemode” model.
If you put a request in on the forum. Post it under the game help section.
Remember to include the character ID number.
