Price range issue

Hi, can you please help me with these two problems:

1. On the page I’m working on, the price range slider doesn’t show the full price range for all products. It only seems to see the first product. I’ve tried disabling a few other plugins, but that didn’t help.

2. Is it possible to have the toggle open by default (and be able to close it with a click)?

Thanks in advance!
