On iMac with Apple Silicon and Sequoia 15.3.1: When I try and change the Legend Key within the displayed Legend of a graph in a spreadsheet, I can make changes to the color, shape, size etc and they are displayed correctly. However the settings are not saved with the document save (saved as .xlsx format) - next time I open the document they have reverted to the default setting. Same on version 24 and just installed version 25.2.2.2
