Hi there,
Welcome to SeaTheme forum.
It’s possible the data wasn’t imported completely. I suggest you edit the single exhibition page, go to BM Content Builder, and delete all modules. Then click “Insert Template” in the upper right corner, the pre-template panle willshow, click the “Inner page” tab, choose a single exhibition to inert. Wait a moment, and the new layout will be imported. Please close the panel, then you can edit the imported layout.
Regards!
