Selector node values are not exposed

Hi Denis, i think i found a bug in the Selector Modifier Node, no Value on the node can be be exposed. The Value field is always greyed out for any Property of the node. All others work as expected.

No special setup needed to reproduce this issue. I am using MM 2.1.5 Bundle
