Hello,
Thanks for using our theme.
Do not use the Delay JavaScript option of the WP Rocket.
We can provide screenshots of settings from our demo site, as an example – https://gyazo.com/20b36f9bf2dd229261329256c9c74f8f https://prnt.sc/GeLDsVfOq47S https://prnt.sc/zTAJUhz0eNq5 https://prnt.sc/f1qQhGpizwoR
Other options you need to test by yourself because depending of 3rd party plugins and additional customization, the situation on our demo and your site are not the same.
Also, you can try to activate XSTORE Ajaxify in the settings of elements (page content) https://prnt.sc/EvzLILwXaCKt
