Widgetkit 2.9 and Joomla 3. Styling error?

Question

css

Hey!
Who used Widgetkit 2.9?
I've been trying to solve this problem for a long time now.
I put myself a widgetkit on any Joomla3 template (and even on Wordpress) and create any component.
BUT it is displayed with incorrect styles? instead of dimming, there is clarification, the icons are completely different, etc.
Not at all like a developer. Widgetkit also comes with a demo package on their Salt template, everything works fine there.
What could be the problem?
I looked at the code - for some reason, the classes "wk-..." are substituted, and the developer has "uk-.."
When creating a component, I select custom, then I select the slides and that's it.
I tried publishing through the short code "widgetkit-1" and through the creation of the Widgetkit module. Everywhere the situation is the same.
