If commissions are free why does a fee appear in the fee column?

I have two problems -
I see fees on open limit orders
Even if fees do exist, why do I see them on open orders that have not been filled yet?

I am using the paper trading API, trading crypto, but I am not expecting any fees

Cryptos do have a small fee right now. Stocks however are commission free.


You can use this page to know how to query how much your commissions fees are as well, if you need this information in your code.
