Sorry - I did try attaching screenshots in my original post but as a newbie I'm not allowed until my 5th post.

My first try was RDU to KEF from 7/25 to 7/29. The search returned "We modified your search and didn't find a match".

My next try was RDU to SZG the same dates and came back "Something went wrong we didn't find a match". I tried again and same issue but after deselecting miles it populated many choices...same as KEF.
