I have frozen Column A and row 2which have frozen but if I scroll within either pane a whole 2nd duplicate spreadsheet scrolls along in that pane. It's only just started happening but I have tried unfreezing and refreezing, uninstalling excel and reinstalling, I haven't got split or page break clicked. It's happening on both my Mac & airbook app but not my Ipad pro app and it works fine in excel on the browser. I have been using this same spreadsheet for years and it was fine, but last week this issue started. It also is happening on any new spreadsheet i set up. I hope someone can help.
