When editing an item type in the staff client, if you have set a remote image url as an icon, that image link is lost, thus removing the remote image. To re-create 1.) Set remote image for an item type 2.) Save 3.) Confirm image is present 4.) Edit Item Type 5.) Go to Remote image tab, image link in field has disappeared Link should persist during editing.
Hi Michael, I just tested this on master and 17.11 and it appears to work alright now. Maybe has been fixed on another bug? Please reopen if it still doesn't work for you.
