Please send reproducible code when you report problems. I am unable to reproduce your problem. It seems to work just fine.

Also, make sure that you understand what you are doing with competing risks analysis. It seems like you do not have any censoring, i.e. all the subjects are failing from one of three causes. Read the documentation of ?crr carefully.
