I download the ics file from the overview page of the board settings and open it with VSCode. It contains double entries. Absolut sure.

I will do that and respond. But i’am not sure if my guess that it may be TZ related is still the right direction. Thanks for your help! 😅 👍 ---

While thinking about possible scenarios for your issue: Please compare any doublet from your ICS file. Does the UID line match, means you have exactly the same UID twice in your ICS file? ---

Hi alfredb, yes. I’ve attached a flie which i cleared from personal data. I did it very, very carefully. Promise. My view is: Line 1-6 incl. and Line 175 until EOF are the correct parts of that file (or what i would expect to get). The part from Line 7 to 174 incl. is double / should not be there. e. g. UID:task-#20-date\_due is in the lower part of the file (and only there) and is correct. whiel (e.g.) UID:task-#96-date\_due is two times in the file. And the first occurence is wrong / double [Download Zip with ics file](https://we.tl/t-FXoICOVX0q) Cheers, Fx ---

I think I got it! Means I could reproduce the dupes. ![](https://global.discourse-cdn.com/free1/uploads/kanboard1/original/2X/1/1d279bce7ac9029f5f1097796582cbcc834f7d8c.png) ![](https://global.discourse-cdn.com/free1/uploads/kanboard1/original/2X/d/da335d7d880f787f5cecca26b94e918c51e38eaf.png) Make sure that the setting ```auto $this->configModel->get('calendar_project_tasks', 'date_started'); ``` is really on _date\_started_. If it is set to _date\_due_, you’ll get the issue. I hope it’s really the same at your site. ---

It is AFAIK only modified by the calendar plugin. If you don’t have, fix it in the settings table of the DB. ---

Hello @alfredb, i changed the options in the `settings` table of the prod Kanboard installation to this new settings: ![grafik](https://global.discourse-cdn.com/free1/uploads/kanboard1/original/2X/2/282d86456fbc3c76f20fc47b77bb380ebbea8230.png) and finally: IT WORKS! 👍 😃 Yes! All doubles are gone with this setting. Thank you very much for your time to investigate this extrem annoying issue! I suppose the existing settings came from one of my calendar plugin tests. This were the leftovers. Cheers, Fx ---
