This is strange! The separation in arc-seconds is given for A-B in the Info screen as 34.6 arc-seconds. This is suspiciously like the 34.6 light-years given by the measure-from function. Hmmmmm.
I noticed that too. I checked Castor and it gave a reasonable number.
It occurred to me that Albireo could be an optical double and that the distance given is actually the distance between the two components in the Z direction.
Looking Albireo up on Wikipedia indicates this could be the case.
"It is not known whether the two components β Cygni A and B are orbiting around each other in a physical binary system, or if they are merely an optical double. If they are a physical binary, their orbital period is probably at least 100,000 years. Some experts, however, support the optical double argument, based on observations that suggest different proper motions for the components, which implies that they are unrelated. The primary and secondary also have different measured distances from the Hipparcos mission – 434 ± 20 light-years (133 ± 6 pc) for the primary and 401 ± 13 light-years (123 ± 4 pc) for the secondary. More recently the Gaia mission has measured distances of about 330–390 light years (100–120 parsecs) for both components, but noise in the astrometric measurements for the stars means that data from Gaia's second data release is not yet sufficient to determine whether the stars are physically associated."
Apparently, the distance between A and B has not been clearly established. It is possible that Sky Safari is using the Hipparcos data and is estimating the distance at 34.6 light years.
As far as your troubles. My version of Sky Safari 6 pro measures the distance between A and B as:
