Hey @Twitch_Adelt! Welcome to the forums!
So the node you’re looking for is “Remove From Parent”. This is essentially a “Delete current copy of the widget” node. 
If you don’t need it for the main menu, when loading in, check for that widget and if “IsValid?” (use the gray macro one, not the blue function one) then “Remove from parent” and if it is not valid, do nothing and move on.
