Hi, I tried right click and say cannot bump fee. No suitable output..
You should get that error when you don't have enough fund to increase the fee to the amount you want.
Can I cancel this transfer or do I have to jut wait for a long time?
As already said, the transaction in question is local. This means that the transaction hasn't been broadcasted to the network at all.
Don't you see the "Remove" option when right-clicking on the transaction?
