Hello,
Thanks for screenshots.
Here is a reply from one of our developers:
“We have found what caused the problem.
You are using extra plugin for adding tabs on product http://prntscr.com/1qw33hq and you are using SPBuilder on your site.
The accordion that your Single product content is created with our builder some extra plugins/actions/filters may not work as they worked with default template.
We have added you a snippet to make it compatible with Single Product builder in the order you asked us to make. http://prntscr.com/1qw2xqq
Now you have review on first position before all Yikes tabs -> http://prntscr.com/1qw38oc ”
