Hello,
Sometimes when things are appearing and working fine under the page builder editors and not on the actual Site preview, it is mostly related to Cache being the issue.
Right now, as we have checked your Site you are not using any Cache plugin directly on your Site. So, can you please ask your Hosting Provider once if there is/are any Server Cache enabled from their end? If yes, then please try to disable it for a while and flush it out completely and then check back your Site completely clearing browser and server cache.
Hopefully, you won’t find the issue again.
Best Regards.
.
