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).
Fee are not calculated in percentage (%) but in size and weight (Satoshi/vbyte).
Also, know that if mempool is congested, the fee will be higher, and when mempool is not congested, the fee will be lower.
Just make use of the fee customization or wait until mempool is not congested. But, if you use too low fee, your transaction may not be confirmed in time.
