[BUG] Huion H1060P - Express Buttons not working as intended

Hi all, everything seems to be working besides the Express buttons. I would imagine that the layout is like this:

[A] [B]                                 [A] [B]
[C] [D]                                 [C] [H]
[E] [F]     but instead its like this:  [I] [J]
[G] [H]                                 [K] [L]
[I] [J]                                 [ ] [ ]
[K] [L]                                 [ ] [ ]

The last four buttons don't write anything at all When checking each button with xsetwacom --get 'HUION Huion Tablet Pad pad' Button button-number, I get this:

❯ xsetwacom --get 'HUION Huion Tablet Pad pad' Button 1
key +1 -1 
❯ xsetwacom --get 'HUION Huion Tablet Pad pad' Button 2
key +2 -2 
❯ xsetwacom --get 'HUION Huion Tablet Pad pad' Button 3
key +3 -3 
❯ xsetwacom --get 'HUION Huion Tablet Pad pad' Button 4
4
❯ xsetwacom --get 'HUION Huion Tablet Pad pad' Button 5
5
❯ xsetwacom --get 'HUION Huion Tablet Pad pad' Button 6
6
❯ xsetwacom --get 'HUION Huion Tablet Pad pad' Button 7
7
❯ xsetwacom --get 'HUION Huion Tablet Pad pad' Button 8
key +8 -8 
❯ xsetwacom --get 'HUION Huion Tablet Pad pad' Button 9
key +9 -9 
❯ xsetwacom --get 'HUION Huion Tablet Pad pad' Button 10
key +0 -0 
❯ xsetwacom --get 'HUION Huion Tablet Pad pad' Button 11
key +a -a 
❯ xsetwacom --get 'HUION Huion Tablet Pad pad' Button 12
key +b -b

I'm not sure why its returning key +X -X for some and for others just X. Otherwise it looks how I configured it via the graphic tablet settings in the system settings. Maybe the issue is that the graphics tablet went through three upgrades? From the 1060pro -> New 1060plus -> H1060P. I got the latest one. And according to the supported tablets, the one listed is New 1060 Plus(which had a battery powered pen and SD card slot I believe. I don't know what other differences it has), so one generation before the one I got. How do I go about solving this issue I have? Thanks in advance! Oh also how do I even use/configure the 16 soft buttons at the top? I assume manually via xsetwacom --set since they aren't listed in the settings?

❯ xsetwacom --list
HUION Huion Tablet Touch Strip pad      id: 19  type: PAD       
HUION Huion Tablet stylus               id: 20  type: STYLUS    
HUION Huion Tablet Pad pad              id: 21  type: PAD

Edit: When checking with xev i get for button A:

    XFilterEvent returns: False

Button I:

ButtonPress event, serial 40, synthetic NO, window 0x7000001,
    root 0x1de, subw 0x7000002, time 19136431, (48,40), root:(1969,66),
    state 0x10, button 13, same_screen YES

    state 0x10, button 13, same_screen YES

So it seems like button I, J, K, L correspond to button 13, 14, 15, 16.

Edit: If I manually try to set something to the keys 4-7 i get this error Unsupported offset into 'Wacom Button Actions' property.
