I imported a calendar from an other identity and now have two.  Next I tried to merge them, but this is not working.  I followed the instructions here (point 31) but it does not work.

I explain.  Lets say we have a original identity (OI) and a imported (II).

The OI has 100 entries, the II has 200.  When I merge the II in to the OI the dialog box tells me it moves 96 files (should be 200 in my mind).  After it completes there are 100 entries in the OI and 200 in the II.  so nothing happened.

Any thoughts or tips how to solve merging the II in to the OI?
