The event can be reproduced by the following ways
1. In the week view, create an event starting at the first day of the week (e.g. Sunday) and which is repeated daily for seven days, so the last instance will be at Saturday.
2. Edit the title of the Tuesday instance using the quick dialog.
All the events would change the title; the first event would still be at Sunday and the last one would still be at Saturday.
The title is changed; however, the instances at Sunday and Monday disappear, and two other instances appear in the following days after Saturday. This way, the last instance appears in the Monday after Saturday.
