Nighthawk R7000 won’t let me port 1-65535

I’m trying to do port forwarding for my nintendo switch and my touter won’t let me port forward UDP 1-65535, the range that it allows is 1 less (1-65534). I contacted my isp and they just told me to contact Netgear since they don’t do port forwarding or something along the lines of that. My previous router allowed for that range, I had that router about a week ago
