Problem with synchronization of recurrent tasks - the recurrence is not propagated from server to em Client

I have just started using/testing eM Client with my hotmail account, and found the following problem:
All my recurrent tasks created on the hotmail server are displayed as non-recurrent in eM Client.
Also, when I create a recurrent task in eM Client this task is replicated on the hotmail server but without the recurrence.
Am I doing something wrong? Or is the recurrence sync feature not supported in eM Client?
