Multisite translations not working for items created via Tailor blueprint

Hi all

I have created site navigation (Menu) via Tailor blueprint, following tutorial at https://www.youtube.com/watch?v=gIyHdRAp4cg and then I have 3 sites, each for one language with different locale. I want menu items to be translated, for each site. But when I save while one language is selected it changes title for all 3 sites, not just for the selected one. I did add “multisite: true” and “translatable: true” for title field, but it is not working. I have latest October version 4.0.21.

Any ideas what am I doing wrong?
