Note: In older versions, the dialog that opens has no tabs, and the drop-down is named Background.
In some graph templates shipped with Origin, a red rectangle is drawn around the legend entry for the active dataset. Various operations such as curve fitting pick up the active dataset by default.

If you wish to turn off the red box, do the following:
In Origin 2018 and newer

In Origin 2017 and older
