Arrangement of participation in the postgraduate seminar (reduction of points) RIGHT ???

Hi, I received mail from the Lankreis today. “Order of participation in the construction seminar” They write me that I already have 16 points in the central register and must immediately remove some. In this letter however, a sheet is included when and how many points and especially for which violation I got. I was caught on the following days by the police and got points: 31.03.2007 18.04.2007 The details of the offenses I once got to protect the zie Loriented discussion edited 21.03.2008 windance/MT-moderation 24.06.2009 *** Here have been more than two years of rest !!! 04.07.2011 30.12.2011 I found the following on the net: The points in Flensburg from irregularity are deleted two years after entry. The condition for this is that no extended points were added during this time, otherwise all Flensburg points remain standing, and the deadline of two years Why do I have 16 points in the VZR (traffic central register) ?? If within two years no new points should be added in my opinion the ones from 2007, 2008 and 2009 deleted – or ? Thank you for your answers Matpol
