Strange indeed!
My 2020 RadMini 4 was delivered in late June 2020 and has the following selection choices: 16 in, 18 in, 20 in, 22 in, 24 in, 26 in, 700C, 28 in
It came from the factory set to 22 inches and that has always worked for me. With the OEM 20 x 3.3" K-Rad tires, my Rad Display mileage usually agrees with my Garmin GPS units within 1 mile on a ~100 mile trip (somewhat dependent on how twisty the route is, but I don't think it has ever been more than ~2.5 miles different), close enough for me.
I'd contact Rad and ask them what's going on (if they even know), I'd love to hear their answer.
