Created attachment 177211 [details] Visual comparison LibreOffice 7.4 vs Office 365
Opening in 365 and editing the chart, 'Add Chart Element' - 'Chart Title' - 'None' and saving. Then it's not showed with Impress. At opening in 365 title is configured 'Above Chart' even it seems empty, maybe this is what makes Impress add the default value.
Confirming in current-ish master.

Created attachment 192010 [details] Simple reproducer This example file shows how the file was created: create a simple Excel chart, then remove the data series name from the sheets B1 cell. This results in the automatic title being used, but being empty. In Word the automatic title is not coming from a backing spreadsheet, but it's a fixed "Chart Title" string. LO emulates this behavior in all of Writer/Calc/Impress, and uses the fixed string in this "empty automatic title" case as well, however this is incorrect when an Excel sheet is being used as data source.
