OSSelector adds permanetly new OS (that does'nt exist)

Hi,
I have Osselector installed with two Win 7 Setups on two different Partitions on the same Drive.
Everytime I start OSSelector from Windows it adds a new Operating System, that in reality doesnt exist.
So I got my two Windows Versions and a lot of non existing Operating Systems.
The Problem is, OSSelector sets allways the latetest added OS as default.
If I delete these fault Operating Systems the come back next start, each start one new OS.
Can anyone help?

Thanx a lot
Marianne
