Blank space under the filter bar in a custom OVP page

Hi all,

I have a strange thing after adding a custom card to an Overview Page. In BAS the application looks good. The deployed version have a blank space under the filter bar.

It is very likely me that pressed the wrong button. I have aligned the min SAP UI5 version in BAS, removed the card at some point and tried various things with no effect.

Any idea or something to look at will be much appreciated.

Thank you kindly in advance.
