Not sure where you are getting that AyaSpace version, but guessing you are not doing it the right way.
The right way is here and the latest version stable is 2.5.0.12:-
Did you update Ayaspace to version 2.5.0.12 ? The way to check the version is to hold down Ayaspace button get to the main Ayaspace page and click the top left hamburger button, which will show a left side menu with power off at bottom and just above that is the version number you have installed.
Also in AyaSpace you can pick to update to stable version or the Beta version.
Also the Antec Core HS and The AyaNeo slide has never had the option you mention regarding the RGB wheel option just a choice of the colours it lists, so not sure if you were watching videos of other Ayaneo devices that allow that or installed some other tool that allows that, but AyaSpace on the Antec Core HS and AyaNeo Slide never had that option that I have seen on the devices or videos related to the devices. The Beta and older versions may have this option so maybe worth trying the current Beta Version (
AYASpace 2.0 Beta Version v2.2.0.58 ) too as that has more things but also not classed as stable so I don't recommend it, but up to you to test. Maybe why I have never seen a colour wheel option on my device with the two versions I had on my device, the one out of the box then the update to version 2.5.0.12. Also YouTube review videos may have also been using the latest stable version that doesn't show these options you mention.
Regarding your control issues I am not sure what you have done too as not seeing any of these issues you mention, I see you have also added this to the Antec Discord chat but will reply here and there I will point you to this comment too.
You can download AyaSpace from AyaNeo on their download page and click AyaSpace to re-download the stable or Beta version.
A word of advice is make sure after uninstalling it to delete these folders it leaves behind I mention below as these store the user/program presets you set before and may still give you the same issue after reinstalling.
1. Download AyaSpace from there
https://www.ayaneo.com/support/download and click AyaSpace and use 2.5 version 2.5.0.12 download to your Windows desktop to make it easy to install again by clicking the screen as the mouse will be disabled when you uninstall AyaSpace.
2. Uninstall AyaSpace on your device, remember you will lose mouse function after that.
3. Now make sure to delete the AyaSpace folder(s) left behind after uninstall in :-
C:\windows\ program files (86)
and
C:\Users\
YOUR ACCOUNT NAME ON THE
DEVICE\AppData\Roaming
4. Reinstall AyaSpace from your desktop.
5. Restart your device.
6. All done and should work correctly in the default state it comes in and any remapping/settings changes you want to make can be done as needed.
