Wifi 2.4GHz question

Is this a problem? I'm using NetSpot. I have a NetGear R6400V as my Mode Access Point and a NetGear X6S EX8000 wifi extender. I have two C7s. My main unit is using Zigbee channel 20. I am getting ready to migrate to a C8. My garage unit uses channel 25. I may repurpose the garage HE once the C8 is up and running.
