Duplicate (and more) events

[Rowin]

Hello,

I'm using EDS calendar integration 0.5 on Icedove 45.6.0 with Evolution Data Server 3.12.9.
It seems that when sync, EDS calendar integration keeps old events and recreate them, so I have more than 20 occurrence of each of my events in my evolution calendar which is quite boring. I have this issue only with my ICS calendar remotely sync from my university so maybe there is something in this way.

Here is my calendar in Evolution (with several copies of the same event) :

And the same calendar as I can see it in Icedove :

Could you get logs for me from 2-3 consecutive Thunderbird boots?

To enable addon logging:

In Thunderbird go to Preferences > Preferences > Advanced > Config Editor
Set entry "extensions.edscalendar.logging.enabled" to true
Close Thunderbird
Start Thunderbird from terminal
Logs should start displaying on the screen.

I have the logs. As they contains private information, where could I send it to you (I'm not used with GitHub, maybe there is some private message option) ?

Thank you

For me, this seems to be tied to a webcal. All of my personal calendars display and sync correctly but the below continually adds a duplicate event. My guess is this happens every time it syncs.
