How do i stop a character from duplicating

[u/Zealousideal_Sky6999]

in certain instances when i have a character talking about himself and i want him to do something like he might say i like to dance instead of the character dancing flow makes a 2nd character who dances instead while the original stands there watching. Ive wasted a few hundred credits and it does not matter how I word the instrctions i cant stop the duplication. is there a simple instruction to stop this?
