Automatic Qt SDK's remains "installed" even after Qt version is deleted

I've updated my Qt 6.2 using maintenance tool to Qt 6.2.1. For this, I've unchecked 6.2 version and checked 6.2.1. Tool did remove 6.2.0 and installed 6.2.1. After this I removed .user file from my project's dir so Qt Creator did show me list of SDKs again. There it displayed this removed 6.2. It is no longer exists on the disk, but Qt Creator still allows to choose it.

Screenshot from settings. As you can see, 6.2 is still there. And yes, Qt Creator was NOT running while maintenance tool was working.
