Arrange tab not working

Hi folks. I am the sole owner of a report and no matter what I have tried, I cannot get the arrange tab to work for me. I’m in edit mode, I’m the owner but no matter what I try, everytime I have multiple charts selected and I click the arrange tab, its all greyed out and I have no accesses to functionality. Would really appreciate any tips on fixing this.

The arrange tab is disabled on responsive reports. Check whether your report is freeform or responsive, and change it if you want!
