Hi there,
Welcome to SeaTheme forum.
Please investigate whether a particular plugin is causing the issue. Here’s what you can do: deactivate all plugins except for BM content builder plugin and test if the issue is resolved. If it is resolved, proceed to activate each plugin one by one and test if the issue reoccurs. If the issue reoccurs with a specific plugin activated, it indicates that the problem is caused by that plugin.
Regards!
