DCU 3.1.2, Latitude 5490, automatic update mode not working

Hi

I have a problem regarding to the DCU (Dell Command Update) app. These are my settings for searching updates:

And unfortunately, they're not working. No updates was found and install. But when I'm checking updates manually, there are few of them like critical, recommended. This settings was manage by creating registry keys. I check them twice, everything is OK in registry. Someone else had this problem maybe?

Kind regards,

Michał
