I don't know why it is different than the rest. You can add an image but there are a number of steps you need to do.
1. Upload the image into the content collection.
2. Go to the image just uploaded to the content collection and select "360 View".
3. Copy the Permanent URL.
4. Go to the calculated Formual Question and right click in the Question Text where you want the image placed.
5. Select "image"
6. Past the Permanent URL into the field "Image URL"
If you have the image hosted on another site you could use that URL instead.
This problem has existed before with other questions types. I think the bad code just moves around. My work around steps are slightly different from yours, but just as painful so it really doesn't matter.
