2020 SP4 BOM QTY header always shows config name

It seems we can no longer change the QTY header to not display the config name. If we double click to change the heading, only the text "QTY" is displayed, when you complete your entry, the config name returns ie: "config-name/QTY" Any suggestions welcome.

The checkbox I circled in the screenshot below seems to do nothing.
