Looks like Sky Safari 7 updated on October 12 to 7.5.0 and the globulars are gone! There's still an image if you zoom in on a target, but the globular symbol of a circle and a cross, along with the label, are missing. For example, check the location of M13. (And yes, in the Settings>Deep Sky, I have Globular Clusters ON.)
