Laggy Choices — Character Customization

I need help! I made my own character customization, because there have been feature updates. However, the choices are like, lagging. For example, when I go to the menu, it pauses, then goes to the choices. The, when I click on “Hair”, it pauses again, then goes to my list of choices. I hope this makes since, it’s just very choppy and i need help!!
Thanks in advance
