Calendar issues after tranfering from torch to Z 10

Bought Z 10 set it up and everything working fine including calendar then I transferred my data from my torch to my Z 10 with blackberry link .... all my apts transferred just fine but no when I hit the add button on calendar it flashes to the add apt screen for a split second then the ap just closes what gives ...... at AT&T's suggestion I did a security wipe back to factory settings and again the calendar worked fine until I did a restore in blackberry link to retrieve my appointments and then back to the same thing I can't add a new apt it just closes ap ..... very frustrated !!
