cscotto, I was experiencing exactly the same weirdness. I have an M2 Macbook Air, with the additional strangeness that when I click on either ‘Save’ location another program is then listed in the user slot I just saved to, and displays an asterisk.
I was using the USB-C connector at the H90 unit, and connected that to a longer USB 3.0 Type A (blue color) extension cable, using adapters. When I removed the USB cable extension and just used a single cable from H90 to my Mac, that cleared up all the weirdness.
Try changing the cable you use, and hopefully that will solve the problem.
