Performance fees not matching up

I am a strategy provider and today I have had the same person copy, un-copy, withdraw, deposit, copy, un-copy again on a loop about 5 times in the same day. I am receiving performance fees for some of this, but it doesn't appear to add up. For example, the most recent time he deposited around $100 and withdrew just over $300. At 18%, I don't understand why this amounts to 3 dollars.

My brain is tired from trading all day, so maybe I am just missing something obvious but I cannot make sense of how this is calculated.
