How to freeze panes with continental nodes

Hi,

I would like to freeze the first row and first column of an Excel report with Knime, but I keep getting this error when I tag them with header and then try and freeze them

Freeze cell A1 means no visual freeze effect. Did you intend to freeze at the top-left corner of cell B2?

I am able to freeze them individually but not together and don’t know why, is this possible?

Thank you!
