Main menu displayed different after change menu co

Hi! Trying to get familiar with the template functions, but now something happened I can't change back :dry:
In template/options/menuconfig/mainmenu I changed from default "Drop-down Menu" to "Horizontal Menu" saved and changed back again to "Drop-down Menu", saved. now the menu on the frontend is displayed differently (not in the nice bokeh style) anyone knows how to change that back or maybe could pass on all parameter settings, so I can change back to the nice view of the top menu? Thanks
PS. here's a screenshot of how the menu looks like!

Hi! have now tried to change the settings of template/options/menuconfig/mainmenu "Drop-down Menu and after many changes I achieved to introduce the default settings of "style1" - here they are.

Is there any problem?

no sorry, this is how i solved it!
