Describe the Bug

I actually used Ansible homebrew module first time when I installed mas, but then I did brew uninstall and manually installed brew install mas. Yet still has list shows duplicated rows like this:
409203825 Numbers (10.3.5)
409201541 Pages (10.3.5)
409183694 Keynote (10.3.8)

497799835 Xcode (12.3)
497799835 Xcode (12.3)
409203825 Numbers (10.3.5)

And I can't understand how to fix it. I have tried mas reset several times. Actually the problem started that on my clean Mac mas list already shows apps installed. So I downloaded manually from App Store and now I have duplicated items.
