Product Button Options for Image and Text or Just Image Not Working

Not sure when this issue started but to have an image show on my custom product buttons I have to set the option to Image and Text. This just displays the Image however, and no text (which is fine for me as I only want the image)

If I set it to Image only then nothing shows on the button, it just shows as a white button

See Screenshots below for issue

Image Only

Image & Text Setting

The header is considered Text… If you set it to image only it will ignore the header field and default straight to the image

Quick photo showinng what is being used.

You proably got confused that the Header and the Text field is the same.
