Monsgeek M1 V5 TMR Scroll wheel not saving

Having some problems with the Monsgeek M1 V5 TMR software in regards to assigning the scroll wheel volume up and down.

As so far, I am able to program the button press to mute which has no problem saving it's settings. But trying to re-assign the scroll for volume up or down it does not save. I've tried programming it, then clicking the retrieve setting and it just does not save. Currently on the most updated firmware.

Anyone have any fixes or work arounds for this? I like the keyboard but I may just return it and go with a custom build instead.
