Why do contexts interfere with AjaxForm on a multilingual site (MODX)?

Question

CMS

Essence:
When submitting the form (whether the fields are filled or not), a pop-up window appears - " I can not find the specified key of form (action). " In another context, the same thing only in another language - "Could not find the specified key of form (action) )."

I removed the contexts (leaving only web) and removed the "Babel" plugin => ajaxform worked like a charm!
Now I don't understand how to make ajaxform work with contexts.
