I updated to the Ubuntu 19.10 beta yesterday, and since updating, the num lock key on my keyboard (DASKeyboard Prime 13 from System76) is reversed. When it is on (indicator light is lit), the numbers do not work, but the arrows, page up/down, home, end keys, etc. work. When it is off, the numbers work and the arrows, etc. are disabled. Viewing the image of my keyboard layout (English US) in the Regions and Language section of GNOME settings shows Num Lock lit up when it is not lit on the keyboard and vice versa.
I use the Wayland session, and this issue was not present prior to upgrading (I originally installed 18.10 and then upgraded to 19.04.). It is not present if I use another keyboard (I booted with a LITE-ON SK-9020 which uses USB like the DASKeyboard.). It is not present while using the DASKeyboard, if I log into an X session, rather than Wayland. I also tried changing the keyboard language, deleting the English (US) language and then switching back (so I am now back on the English (US) layout). That did not work.
I ran the commands specified on the Ubuntu Wiki's debuggingKeyboardDetection page. The output of lsusb -v is attached as an attachment. I do not have gconftool-2 installed, so I did not run that. The output of xprop -root | grep XKB > ~/xk is:
_XKB_RULES_NAMES(STRING) = "evdev", "pc105", "us", "", ""

I have also noticed that the num lock button seems to sync properly IF num lock is off at boot. If I turn num lock after boot, then the key and indicator light function the way i expect (light on == numbers; light off == arrows, etc). If num lock is on at boot, then the indicator light and key are reversed (light on == arrows, etc; light off == numbers).
