Hello
Sorry for the unwanted delay.
Q1. They are not clickable (seem to be behind the menu):
Because you are using the default header, which has been set as the top most element of the page and you have enabled top1 & top2, which again by default they are placed in top most position. Both section are placed in the top that is why they are on top of each other and one i clickable. You need to set margin-top css rule for the section that contains top1 & top2. The value of the margin-top will be the height you have set of the header. So that the top1 & top2 is placed after the header.
Q2. The background of the modules is gray, where can i change it to transparent so that my background of the page builder is exactly like it is in the menu behind it?:
Could you specify which modules you want to make transparent?
Q3 where can I set which social icons are displayed?:
From "Template Options" go to "Basic" settings. In "Social Icons" section remove the string "#" from the address input box of the social sites you don't want to display.
Q4 the format is very bad (where can I adjust it? which css formats?):
Kindly check the following two screenshots below - they are taken from the "Wimble" template preview page. I have highlighted some sections with yellow rectangular box. These are the contents of "top1" & "top2". And this is how they are designed to use in this particular template. That's why they are rendered this way in your site.
What you can do to improve is build a custom SP Page Builder type Module that will contain social icon group & button group addons. Kindly check the screenshots below. I have tested this in my localhost. See how it rendered in the final image. And I have set it to be positioned after the header menu - so they don't render in the same position.
