Hey there, this unfortunately is a bug that isn't exclusive to only starters. If relogging and leveling up the pokemon doesn't work, you can open a ticket in the discord server where a staff member can help you out :)
Is this still an issue? If so I highly suggest opening a ticket in the discord so a staff member can walk through it with you and potentially find a solution :)
A good idea would be to send the screenshot to staff members via a ticket in the discord so they can handle it appropriately. Calling other people offensive names like that is definitely not allowed
