Using a DM setup the values under Administration -> General are confusing / wrong

1) As soon as I formed the DM env by creating the nodes under "Macros" you suddenly see 2x "

2) When then adding a new macro on the master node it also apperas in the GUI of the child node but it seems not to be usable.
I now have also defined seperatly on the child and it technically works but when I look on it from the master node I've got every entry duplicated

3) Value mapping the same issue.
Created one on the Master node, it does not appear on the child, but whe I try to create on the child it claims that it allready exists.....

How does Value Mapping, Macros work in a DM setup with Zabbix 2.0 ?

Best regards,
