Can't withdraw SJCX due to "not enough bitcoin for transaction"

I’m trying to move my SJCX around in preparation for the move to the new token, and to do so I’ve transferred a proper amount of BTC into the same address that holds my SJCX. Regardless of whether I use normal fee, cheaper fee, or custom fee (between 100 and 150) I always get an error stating I don’t have enough BTC, even though I do. For instance, needing .0003774 when I have .0005887 in the address. I appreciate anyone’s help!

The fee calculation has a bug in sometimes.
Maybe try another wallet like or instead.
