Infinispan Extension does not use named Caches

I Setup a Infinispan Server locally on my node and start it with ./standalone.sh -c clustered.xml
There a a clustered Group, and inside the Default Cache and my Manual created "Helios" Cache.
If I use a named Cache in the CachePut, everytime the items will be stored in the detault Cache. (What I can see from the statistics page, Cache hits, read, write etc)
