Hi you,

#1. Your product image is in .webp format, this format is not supported on safari browser so when you visit the website on this browser, the product image will not be displayed.

#2. You mean the checkbox cannot be selected at this position: https://prnt.sc/8ht8CsPmpgaq
This is only the display option for the categories next to it, not the checkbox option.
To use the filter function by many other attributes, you must use a filter plugin
