How to hide labels under transparent polygon layers

This is probably a rediculous and simple question but I don´t seem to find an answer though browsing through forums and help-pages:

My problem is that my labels (for example contour labels) don´t respond to the transparency of the polygon layers above the labeled layer.
I attach a snapshot to explain better.

The contour lines are nicely just visible below my yellow and green coloured polygon layers set with a 10% transparency, BUT the coutour labels are clearly visible just as if they were above my polygon layers. How do I get them to have the same visibility as the contour lines?

I use ArcGIS for desktop Basic v. 10.2 (with maplex)

Thank you!
