Wrong time zone

After importing an ics calendar the time is shifted by 2 hours.
Actually this worked before but I just noticed the bug

For example this ics formatted date:
BEGIN:VEVENT
SUMMARY:Herren 1-TTC Reutlingen 2
DESCRIPTION:Herren 1-TTC Reutlingen 2
UID:17true_Herren1-TTCReutlingen2@tt.tvderendingen.de
CLASS:PUBLIC
CATEGORIES:Tischtennis, TVD Tischtennis, Herren 1
DTSTART;TZID=Europe/Berlin:20171008T143000
DTSTAMP;TZID=Europe/Berlin:20170911T233443
END:VEVENT

is displayed as 8. Oktober 12:30
but 14:30 is the correct time.

Is TZID=Europe/Berlin not recognized anymore?
I used this ics formatting since years in JEvents. And it worked correctly - but today I noticed this wrong time shift.

Any help is appreciated
