I Do you not want to pay 7% in fees? If not then you can move the slider that should appear to within 5 blocks (an hour) or 25 blocks (5 hours).
I have never used such electrum before, or you are confused. Fee are not calculated in percentage (%) but in size and weight (Satoshi/vbyte).
Also, know that if mempool is congested, the transaction will be higher, and when mempool is not congested, the transaction fee will be lower.
Just make use of the fee customization or wait until mempool is not congested.
