Can't the Custom Property and Component Profile be used together?

I used Component Profiles to make it possible to select the OS when the VM is deployed.

I also used Custom property to select datastores when deploying VMs.

However, if I select something other(In my case, Windows-Server) than Default value Sets,

The Custom property value is empty and the VM is not placed on the datastore I selected.(3PAR-LUN5).

If I deploy as a Linux Template selected as Default Value, the VM is normally deployed on the datastore I select.

How can I solve this problem?

Please give me a lot of advice.

Many Thanks
