Hello,
Thank you so much for your help with the query. Most of it is working, just that there are a few more concerns. Please find the screenshots in the email.
1. What I meant was when the categories are selected or clicked upon, in their selected state they are showing up in white on the sidebar. 
2. After I’ve selected the effect Default, I’m facing a certain issue. I want to remove the option “Sold By: …” from the options, given there is only one brand we don’t want to show it on all products.
3. There seems to be an issue with products related to Volcanic ash, please help me resolve the glitch. I don’t understand what is causing the issue. Please check the sub-category Volcanic ash through the Shop sidebar.
4. For point no 6 please check the attached screenshot. 
5. Please check the private content area for the credentials.
