Hello everyone
In addition to the standard Woo stock statuses, I also use custom statuses on the site.
When filtering, they are not displayed now. The _stock_status field has only the instock, outofstock, and onbackorder values available in the filter.
It would be convenient if the filter also saw custom stock statuses and displayed them.
Thanks!
I will add one more point here.
When saving a template that has filters, they are always regenerated. I think filter regeneration should be made optional. If I haven’t made any changes to the filters, then I don’t need to do any extra work.
When adding 6 Checkbox + Taxonomy filters, saving the template freezes and it is not saved 

I have a large number of products on my site and the constant regeneration of values with each save leads to a freeze.
