Cockpit shows blank field for end users

[Madest1]

Hello!
I have a problem with my local Knowage 8.2 communty instance. The problem is in cockpit report for end users. I've made a text widget with report in cockpit under admin. There are some datasets and analytical driver. For admin this cockpit works perfect. When I switch to 'user' role I can execute my cockpit report from functionalities menu, but insted of widget with data i get blank field.

I gave the right permissions for user (selected default dataset category), all my datasets are 'enterprise' and are visible for user in 'my data/enterprise' menu (user can execute them), analytical driver is accepted for user, the document is in 'released' state.
And the other thing is when I make a new cockpit as user I can't see datasets at all, neither enterprise nor shared. But in Geo-referenced analysys i can use all datasets. So it seems that the problem exactly in absence of datasets in cockpit. In Knowage log i have no errors, only in web browser (in attach).

What is the problem it may be?
