Reply to Route FX bank (Bug?)

Hello I was watching the tutorial VCI-100SE Mapping Tutorial Pt. 2 and in the video at 3 min. there is a option to see which effect bank you are controlling.
When I press the button no lights are going on or of.

By example when I am using FX slot 2 on deck B there is no light under the B knob, is this a bug? I am using the latest firmware and mappings, and the light are not damaged.

Best regards,
Darius B.
