I am using EpiServer 7.5.   

I have a PageModel with ContentReference field for images.    I want to have the functionality so the Image for the Page is optional.   So they may not have an image at all.   If I have the page built, I notice I cannot remove the image if it was saved and save it at that state.   I click on the X button to the right of the field, which clears the fieldout.    If I try and save and publish, when I come back to the page... the old value is still there.     So it doesn't seem like the X button does anything.

If necessary, I can just edit the raw value, but not sure where to go to remove the field value.
