Missing $ when leaving tables on WPT

I've played on WPT and recently noticed a discrepancy between the amount I leave a table with (in CNY)
and the amount WPT gives me in USD.

I play mid stakes 25/50/100 CNY stakes and recently left a table with 10776 CNY.
WPT records indicate I cashed out for $1507.48 USD.

However, this amount actually converts to roughly $1522 USD.

To sit down at the table a minimum of 5000 CNY is required. WPT indicates this equals $706.02 USD.

Doing the math, a single CNY equals 0.1412 USD.

Multiply that by 10776 CNY which I left the table with and you get $1521.6.

I am out about $14 or $15 USD.

What is going on here? Am I missing something? I thought about rake and WPT indicates that for these stakes of 25/50/100 CNY.
the max rake is 100CNY with 5+ players, which my hands have been.

As I understand, the final amount you have after the hand factors in the rake which has been deducted.

I also have records of another hand and it appears I'm out even more, maybe $18 USD.
