I had some stacked up tiles which I wanted to wrap up with an outter container .schedule which I have done successful.

I also have some tiles lined up at the bottom holding same info, and wanted to wrap these with the same outter container .schedule, but have failed. for some reason it seems to have shrunk everything nested inside.

I followed the same methodology of changing the #contentContainerTopLeft .event-header to #contentContainerTopLeft .schedule and thought it would work for #contentContainerBottom .event-header to #contentContainerBottom .schedule

The approach worked work #contentContainerTopLeft but failed for #contentContainerBottom

Am I missing something here? Where do I need to check and look? In need of expert advice. Attached is Before and After screenshots with before and after codes.

Any help and advice or solution would be greatly appreciated and many thanks in advance.
