Mouse natural scrolling setting and compose key setting lost after reboot

Hi,

I never reported a bug for Ubuntu. Therefore, I would like to clarify whether this actually is one and what information is needed for submitting one.

After every reboot of my Ubuntu 20.04 system, the settings for natural mouse scrolling and the compose key are reset (at least this is the ones I know of). This means that although I had natural scrolling activated when shutting the machine down, it is not activated after the next boot. This is the case although the switch in the system settings indicates that natural scrolling should be activated. Toggling the switch (i.e. turning it off and on again) leads to natural scrolling being activated again. The same is the case for the compose key, set through the "Tweaks" application. Although it shows "Right Alt" as compose key after reboot, the right alt key is not working as compose key. Setting the compose key to something else and then back again to right alt solves the issue, and right alt is back online as compose key.
It is annoying to toggle both these settings after every reboot.

Am I doing something wrong or is this a bug? Happy to provide further details if needed.

Thanks in advance!
