You may have inadvertently edited the default label style. If you select “edit” when you click on a style, you’re changing that style across the whole platform. Two ways you can go about using different styles. 1, you can create a style (I’ll usually find the default style for that widget, duplicate it, and make necessary changes and save it under a new name). 2, remove the style from the widget, click on the wand on the right side of the style box, and choose ‘Custom’ style.
