Hi,
I believe there's an error with U Cygni.
In ST3 and ST4, the double shows WDS discoverer code as BUP 183.
In the WDS, BUP 183 appears as 18344+2615 BUP 183 in Lyra with a precise coordinate of 183429.15+261515.1. It is a quad with stars between mag 10 and 13.
ST4 shows a single star J183429.1+261515 at this location. Nearby GSC 02115-1743 appears to be the B star and J183432.6+261619 the C star.
U Cyg should be BLL 49. aka 20196+4754 BLL 49.
