duplicate and wrong Inventory information

I have a couple of PCs which show duplicate entries in the inventory list of one device - of course they are really on 10.3.4:

ZENworks Adaptive Agent, Windows 10.3.2.41992(C:\Program Files (x86)\...\bin)
ZENworks Adaptive Agent, Windows 10.3.4.13979(C:\Program Files (x86)\...\bin)
ZENworks Bundle Module 10.3.4.13489(C:\Program Files (x86)\...\modules)
ZENworks Distribution Point 10.3.2.948(C:\Program Files (x86)\...\modules)
ZENworks Distribution Point 10.3.4.13352(C:\Program Files (x86)\...\modules)
ZENworks Imaging Agent 10.3.1.68101(C:\Program Files (x86)\...\preboot)
ZENworks Imaging Agent 10.3.1.23161(C:\Program Files (x86)\...\preboot)
ZENworks Imaging Module 10.3.4.13489(C:\Program Files (x86)\...\modules)
ZENworks Inventory Module 10.3.4.13489(C:\Program Files (x86)\...\modules)
ZENworks Personality Migration 10.3.0.58097(C:\Program Files (x86)\...\Personality Migration)
ZENworks Policy Module 10.3.4.13490(C:\Program Files (x86)\...\modules)

ZENworks Wake-on-LAN Handler 10.3.4.13490(C:\Program Files (x86)\...\handlers)

How can I get rid of the wrong entries? Inventory update is performed twice a week.

Servers: 2 prim Server w2k8r2sp1 with ZCM 11.2.2 with MS-SQL 2008 DB
Clients: mainly Win7 64bit SP1 with ZCM Agent 10.3.4 -waiting to upgrade to 11.2.3 due to multiple reboots for previous versions.
