Could not restore default Jetway in KMEM

Stock Jetway in KMEM that I tried to adjust.

I had to restore my entire Hard Drive just to get that one jetway back like it originally was and it has, I did it the hard way.
I've read some previous posts here about this but the description of pressing a restart button was a bit vague to me. I glanced over the GSX manual on how to make
changes and a reset was mentioned. I tried to make the GSX panel to restore and all when I went back to my saved settings the messed up jet way reappeared.
Somehow, the jet way had a custom logo on it, did not know how to get rid of it and go back to a blank one. So, I would appreciate info as to how to get the defaut
jet way back. As I mentioned, I found the section in the GSX manual on how to do a reset but when I thought I was doing that, nothing changed. Please have bear with
me as I tried all the keys offered in the edit mode and did not have any luck. Thanks.
