That the exp shows "-----" is normal, since your character has reached the highest level, meaning they can't earn more exp than that. Try out if you can use the EXP for something now, if you can't, please tell me!
oh no don't worry you weren't rushing me at all! I have a lot of school work right now so i didn't get a lot of time to try it out but i didn't feel like you were rushing me!!
