We’ve made some additional research about the problem and came to a conclusion that this is not a theme related issue, but rather a server one.
Product quantity change triggers an AJAX (server) call. When you spam the server with many queries in small time period, it lags and latest queries are not processed. We’ve tried to increase the memory limit from your php.ini, but with no success.
What you can do here is to ask your hosting provider about some server limitations that can provoke this problem.
Please find the feedback as below:
1. I edited the core files and removed the dots. thanks
2. Can you advise on the area controlling the size of description text in Product Listing? I’ll try to make it smaller.
3. I added extra CSS into the Custom Stylesheet section. However, the text are still aligning left.
Can you please help to have a look?
Thanks a lot!
