[Cubase 10.5 Pro ]Something wrong with CC1 and modulation wheel

So, I suddenly faced a problem with my ModWheel. It worked well until this day, I never used “midi learn” or any other way to make ModWhl work with all VSTs. It worked just from the moment when a project was opened.

Now it doesn’t. I can see that Cubase (and all VSTs) got the midi data from my keyboard-wheel, but it doesn’t change anything.

BUT! I tried to learn midi and I noticed that my MdWhl controls CC4 Foot (and I don’t know why). How can I fix this issue and return my MdWhl to the CC 1 Modulation?
