One thing that seems to create some issues is that D1 and Sat 19 settings are very close when trying to set the dish

 

skew is about 6 looking from the back of the dish and about mid point on the LNB for the bracket

 

They're plenty far enough apart to not get any signal from each other though. More space there than D1/D2 for example. Are you moving the dish each time you want to change satellites? If so, no wonder you are having issues becuase it takes time to properly realign it for maximum signal each time.
