Hi B,
So if I’m understanding things correctly the issue is with the missing title (the actual <h1> </h1> tags are present – but devoid of any text – reducing the total height of the container)?
I think what you will need to do here is firstly identify where in your theme that content is populated and then determine a means to change the text/add more meaningful text.
In the context of event pages, you might be able to use the tribe_is_event_query() template tag to help you determine when and when not to modify this entry.
I’m afraid that – not being familiar with your theme – we can’t help too much with the actual process of customizing it.
One other thing you might try is editing the template setting in Events → Settings → Display and toggling between Default Page Template, Default Events Template and any other options that might be available there – sometimes playing with this can resolve problems like this one 🙂
Does that help?
