Problem Inserting Image from Computer to Enterprise Wiki Page

When I insert an image "from Computer" it seems to work fine, the image appears on the page and has an associated address/link.

After saving, the image disappears, replaced with a broken image icon and image name.

Back in edit mode and it looks like the address/link is gone.

The image has been saved in a folder in Images in Site Contents, so I can find the address and re-link it.

It is a lengthy process, is there a way to avoid the address/link being deleted?
