multiple reminders added, impossible to change time

SUMMARY
***
When creating a new event, there are only two options for a reminder: a) not to touch it and stick with the default 15 mins or b) try to change it and get "at time of event". Regardless of selection, reminders are not saved.
***


STEPS TO REPRODUCE
1. Create a new event
2. The reminder is set to 15 min by default
3. click on the selection bar and select any amount of time
4. Reminder is always set to "at time of event", regardless of actual selected time
5. Additional reminders can be added, but also only for "time of event"
6. if adding a second reminder to the default one, this also can be set only to time of event
7. The maximum number of possible reminders to set is therefore 2, but:

OBSERVED RESULT
No reminders are saved at all, regardless of setting one or two.


EXPECTED RESULT
1. multiple reminders should be possible
2. the user-chosen time of reminder should be honored
3. all reminders should be saved.
