Product image, title, price not showing

I am working on this page and this drives me crazy. Product image, title, variations and price are not showing on preview or live. Sometimes it shows on preview but then disappearing later. Everything is up-to-date and I have no idea what else I can do. It looks like the whole container is missing except product description. Please let me know about any ideas? Maybe it is a common issue, but I cannot find the same problem in the forum.
