Localization package broke inspector fields

I have just installed localization package and used it nicely so far. But today I got this issue.


Every time I try to change any variable in the inspector, it spawn the Game Object Localizer (Script) component and spam errors on trying to change the value.
For example if I am reassigning gameobject

Relaunching the unity helps to get rid of this behaviour, but only for some time. Any ideas how to fix that? What additional info I should provide, if any?

It seems like the core of the issue was me “accidentally” turning this option on without realizing what it’s doing at the end of last session.

My bad, this issue got me really confused for a while.
