requesting for some changes

im using this plugin for a while and besides its advantages i face 4 tiny isues and I appreciate if you can address any of these,
1: this option from sorting filter “in stock always show first” is not working by default, it only works when i change sorting atleast once

i preset sorting on newest products but in result available products are mixed with unavailables

and now when i change sorting once it works fine and sort all availables first (for example in this picture i choose 2nd sorting and again go back to first sorting which is newest)

2: im using sorting filter in a group of filters and i turned on “display selected parameters of filters” option for the group but i want to turn it off exclusively for sorting filter, can u please add an exlusion inside sorting filter option or is there a code to turn it off only for sorting filter?

3: stock status filter (in-stock toggle) correct me if i misunderstood of what i expect from this option
is to show only available products and hide the rest,
instead its showing all products (available & unavailable) and then sorting available products first

4: for price sale filter (in this case filter skin is set to big skin) i need to swap the position of lower counters (for rtl) and the numbers should start from middle or left
