Invalid Notification volume is controlled by Media volume on stock MIUI11

[uvuvuv]

Dear XIAOMI,

Model: Xiaomi Redmi Note 8 Pro 6/128
MIUI: Global 11.0.2, Stable(11.0.2.0, PGGEUXM)
Android: 9 PPR1.180610.011

Why would Note 8 Pro's notification volume is controlled by media volume?
For example, when notification received from Facebook or such, its sound is muted or when trying choose a notification sound in settings it shows toast "Ringer is silenced".
When media volume is increased everything works, but this will play from videos or music player with sound through speakers which is not what is needed!
Current volume settings:

Spoiler: Show message

Is that a bug?! If so, how to remove that then? All updates are installed and phone was bought less than a week ago.
How would it be possible to separate them? What then these volume bars mean?!

Thank you

Thank you. Yes, but where to ask that then and is that a wrong place, really?

This is a custom ROM. You need to go to Xiaomi official site.

This website is called Xiaomi MIUI so why this question is invalid if asked about Xiaomi MIUI?

Because we're not Xiaomi. This is Xiaomi.eu custom ROM project. Not official.

As @Igor Eisberg said and I mentioned above in post #4: These here are custom ROMs, not Global ROMs.

Understood. Thank you. Where to find if it is global or custom on the website?
How to close/delete this thread then and where to ask such then?
Also, it's worth to mention that your post editor and engine is quite awesome(XenForo, huh?)
