When using connecting to ASM and having tns entry strting with prefix test_ then ASM does not work (does not diplay values - it is grayed out)
The issue arose because of a temporary connection we make as part of the pre-test we do for the Connection Details Verification Dialog.
tns entry for asm connection cannot cannnot start with Test_ e.g. It means you can have for example test1_ or ASM_ and then retry the connection (applies to both 7.5 and 7.1 versions).
Note: you will need to update the asm connection string in the connection profiles before making Spotlight connections.
