Bug Unity 2019.3b10. Localization is unusable.

I'm using 2019.3b10.
I followed tutorial for 0.5 version.
I can't edit tables.

That's how window looks.


This is the error in the console:
(Seems like argument 'index' is equal to tables count)

Code (CSharp):

1. ArgumentOutOfRangeException: Index was out of range. Must be non-negative and less than the size of the collection.
2. Parameter name: index

Only 2 locales. Starting from 1 table (no matter string or asset) it throws this error.
Also, I tried to use 2 different table types. That also doesn't work.

And when I had 2 tables I tried to change package code to debug value of parameter 'index'. For 2 tables the index equals 2.
