I have been experiencing a strange, and I think related, issue with double stars in observing lists. The list in question was a series of entries from the WDS catalog, which I imported into SS6 and which imported with no problem. As usual, I selected the "highlight objects" and "hide observed" options to allow me to work through the list efficiently. SS6 showed all of them on the sky map and did a perfect go-to on each one of them, but when I attempted to enter a new observation, (1) it did not recognize the object as being on the observing list I was working from; (2) when I tried to designate the observing list manually from the observation page, it told me the object was not on the list and prompted me to add it; (3) now each object is showing twice in the observing list, with a check mark beside both instances; and (4) the object are not hidden in the sky map.
My suspicion is that this is cause by a failure to relate the various catalog numbers that accompany double stars, although I can't be sure of that. I am running SS6 Pro version 6.1.0.34 on a Samsung Galaxy Tav S2, Android version 7.0. It would be great if this issue could be fixed. Thanks!
