Yes  Sebastian. I am also wondering why is this happening. As I feel, it is clearing the cache after a few seconds (or happening something like that.)

That is why the value is empty.

This issue came after upgrading to DNN 7.0.6 version.

Do you suggest to setup a fresh DNN copy and move the content there? or any easy way to avoid this issue?

Lot of tabs would be an issue?

Thank you for your advises.

Ok  Sebastian.

If i upgrade to a newer version than 7.0.6, then will this issue fix? I had some issues with 7.1.0 version when modifying the content and popup editors. So I revert back to my site to DNN 7.0.6.

If there is a possibility, I can provide you login info through a private message.

Thank you very much fr your support.
