Widgets make other plugins’s icons in visual editor disappear

Certain widgets of the bundle (maps, editor, contact form, testimonials, hero) make many of my other plugins’ icons in the visual editor disappear (e.g SportsPress, Page Scroll to id).

Tried this also on a fresh install. Issue still persists, and only goes away when I disable the widgets or disable the whole widget bundle plugin.

Could anyone help me fix this?
