How to reproduce it :

• use the demo repository
• launch a search of all contents with "News" tag.
  > the result is ok
• edit again the field "tag" to add a tag
  > the "News" tag is not selected anymore whereas, we see that it was selected on the previous research. There is no tag selected.

Expected behavior :
The selected tag should stay selected. I the user want to unselect it, he can use the checked button.
