Thanks for the reply.
1/ Provide temporary wp-admin and FTP access to the site where XStore is used.
2/ Provide URL of product from the dummy site where we will be able to see the mentioned feature.
Also, provide screenshots, it will speed up our work. You can use Lightshot screenshot or Gyazo tool to share links to your screenshots.
Only after that, I will be able to pass your question to our dev team.
