Just following up on this in case people see this in the future. When you setup your wifi router as WPA3/WPA2 that essentially put it in the “OWE Transition Mode” descripbed in the Huawei paper linked above. From the perspective of WPA3 (which is effectively just another name for OWE), you enabled OWE, which is why the wifi analyzer saw OWE for your network. In WPA3/WPA2 mode, the newer devices that are capable of running OWE, do, and the ones that do not have that capability, obviously do not use it.
You need to be in WPA3/WPA2 mode until you have removed or upgraded all devices on your network to ones that are WPA3 capable (or don’t mind them simply being disconnected when you change the wifi router to just use WPA3 only).
