I'm using Impulse theme for my website, having a lot of Hebrew in it (with rtl support)
trying to filter products using multi select, with a hebrew tag (non roman letters language), the whole sidebar of filters disappears. filtering with english word, works just fine and returns hebrew values aswell.
my website collection page - https://365mashbir.co.il/collections/spvrt-1
Sorry for the hebrew in it. filtering on the right (נשים = women, גברים = men).
under "מותג" there are many english words to try out.
This is something that you'd want to reach out for the Impulse's developers for a proper fix. It seems likely to be a bug, so they should get it fixed for you and subsequently all the other users, or at the very least give you some clarity on how to work around it.
