Transparent header settings

Hi, I try to make my website like the Enfold Transparent header.
I can’t figure out the right settings:
The transparent logo I have uploaded.
– The header behavior: what settings are used of the 3 options? (sticky etc)
The transparent logo still shows over the normal logo once I scroll down:
– How to remove, so that the normal full logo is shown?
– on the homepage I guess, transparent header needs to be set on?

If I look at the website of http://frontdesign.in, the I see 2 different logo’s. (which one is the transparent or normal logo)
What is there the setting?

I hope this is not too much to asked. I tried all the options and read the posts, but still can’t figure out the difference.

Thanks!
