I've used hierarchical blocks but have never seen this issue where the block doesn't link to the schematic. After placing normally double clicking on the block will go to that instance of the schematic page. And when right clicking you synchronize and descend are not greyed out. Any ideas why this might happen? Here is a screen capture of the grayness.
