#1446 Calculator: Unchecking or deleting fn leaves it on menu

[The Shady Watcher]

If I record a simple function that only hits multiply, name it "a" with a description "a", go into the Functions editor and uncheck it, and hit "Apply", it does not disappear from the menu. Returning to the Functions editor, it is again checked. If I instead uncheck it, hit "Apply", close the Calculator, and reopen the Calculator, it is now not on the menu, and not checked when I go into "Functions ...".
