Problem with ICS files, reccuring dates with EXDATE and RDATE are wrong

I’ve got an ICS calendar file wich creates missing dates in emclient. Event contains EXDATE and RDATE für exceptions of a reccuring date. Problem is also generated (i suppose, it’s the same), when changing one of a reccuring event in a google calendar.

Here is one of these events: (Example: one event is moved from 2017-apr-21 to 2017-apr-22. But it’s not displayed in emclients calendar!)

Thanks for help or information how to solve this problem…
Regards, Christian
