Speed dial / Thumbs won't delete

Hi,

In the new version appears new 2 speed dial button, or they not new, but they now used by whatever history search.
It could be search from 2 weeks ago, or recent, unpredictable.
When you try to delet them, they go, till next time you restart your brouser, or open a new window.
I cleaned history, reinstall Comodo, nothing helps. They are here.
Really annoying.
What to do?

Comodo Dragon v89.0.4389.128 64bit, Win10 pro 64 bit.
