Hueman Addons 2.0.10 ceised live prewief of themes

Hi friends,

I use child theme, wp 4.7.4, addons 2.o.10

Since I updated the Hueman Addons to 2.0.10 both of my WP 4.7.4.sites showing maladjustments regarding theme previews. One site is with Hueman 3.3.7, the other with 3.3.10. The result is similar on both sites.

If I switch to another theme live preview in WP dashboard > Themes, nothing appears on the screen, I mean left-side panel of the selected theme is visible but no picture of the site, just white empty place.
If by troobleshooting, I disable all plugins, the preview comes back. When I start to reactivate the plugins 1by1, the preview is going off again when Hueman Addons is activated. I checked this using default WP twenty-fourteen, fifteen, sixteen and seventeen.

(1 day ago I made the same tests with H.addon 2.0.8, and live preview for default WP themes was OK.)

This happens on my both sites, also with 3.3.7 and 3.3.10.

I don1t know if there is any influence to the above, but I discovered another issue as well.
If I switch to core Hueman live preview, the content is visible, but comparing to the child theme sidebar content, some widgets disappear and new widgets showing up instead. But I have never added this new widgets to the sidebar!
Or its better to say widget zones as a.g. there is a meta widget appearing in my footer widget zone, though my footer widget contains a html/text widget in real.
If I switch back to child theme, all display and functions are OK.
I have no clue, how this might happen.

This happens on my both sites, also with 3.3.7 and 3.3.10.
