Suggestion: class wise image uploads grid shows blank if none is selected

Steps-

1) Select a company whose company logo you want to change.
2) Goto Customizer >> Upload Images
3) Expand 'Company Logo' section
4) in selection select some class and for other class select none or do not select any >> save
5] in grid view where none is selected nothing comes, see attached

in case of 'None' selection it would be better if we display some info rather than showing it blank
