[Closed] Filter everything filters not translting

I have a series of Filter Everything filter-sets, which I apply to two Elementor Archive pages.

It was all working fine, but now it is not.

I have tried deleting the translations permanently, then recreating them with automatic translation, but none of the filters in the filter-sets are included in the translation.

The only thing I think I may have done is to switch the main language from English to Russian, but everything else works fine.

Help!
