After having upgraded to 6.2 the following issue happens in Web Content Management:

1.) Edit existing article with a picture assigned. (See Screenshot 1).
2.) The Picture reference Name is missing in the edit Dialog box (see Screenshot 2)
3.) When Publishing the article, the Picture has gone. (See Screenshot 3)
4.) When selecting the Picture again from the Media Library, then it works.

Reproduction:

Launch a 6.0.12 instance
Upload an image to the Image Galery
Create a structure, add an Image Galery field
Create a web content from the structure, select an image from the Image Gallery
Upgrade to 6.1.20
Upgrade to 6.2.10
Issue: Edit the web content and observe that the image title label is empty
