Hello,
Unfortunately, if you use custom reviews tab as the part of the description there is no way to get scroll to it because that tab has autogenerated anchor http://prntscr.com/krarz9 as this is WPBakery element and it’s not the default tab. 1) Reviews tab should have the regular id to allow the script to scroll to it. 2) You should create script that will scroll to your custom tab with regular content once you click on reviews link.
After clicking: All the tabs and content are gone (including the “Reviews tab”)

It’s because you have hidden real tabs titles and create Reviews tab as custom tab using the WPBakery element that is added into first description tab. So once you click on real reviews tab the description tab content is hidden and real reviews tab content is shown.
We have added custom to change style if the real reviews tab content if you choose after the tabs reviews position. But we found bug that it does not scroll to reviews but to tabs only when you click on reviews link. So, provide me FTP access to your site to fix this issue if you decide to show reviews below the tabs.
