letter r at ending of appointment lines


I have zarafa mail/calender software running on a synology nas. In this calender I already had a lot of appointments before I installed emClient.

When I open such an appointment, there seems to be a letter ‘r’ at the ending of iets line (except) the last one.

Is there something I can do to change this or is this a bug ?

Hello Bernard,
could you screenshot the issue for me or send me an ICS file of such event to rust@emclient.com, so we can get a better idea about this issue?
