SUMMARY *** I use radicale (used to use google calendar) and I will have recurring events for my schedule for example meal prepping every saturday. Well....this week I want to mealprep on friday so i make the change in a calendar client (kontact or google calendar) I will make the change to modify the event once on the 4th of march to move it to the 3rd NOT to modify all events just this one specific one.....KDE calendars will show the 4th still has mealprep, and so does the 3rd. I tried with google calendar and radicale - it is the same result. *** STEPS TO REPRODUCE 1. Modify one event of a recurring series in a calendar client 2. Wait a few minutes for it to update in KDE calendar client 3. OBSERVED RESULT Show incorrect data EXPECTED RESULT Show the change dont show it for the 4th and the 3rd.
