Q: In the “Edit module” window a caption was added a second time. How do I remove the extra one?

“＋ Label” always adds one more caption, even if one is already there; the tick in the list only shows that it is already in the module. The extra one is removed by the “Remove label” button on its row, while the eye “Hide (keeps its settings)” only hides the caption on the chart. A module holds up to 8 captions; “Done” saves the list, “Cancel” discards the edits.
