Mob spawners ignoring light levels?

[Xellas]

Loving the pack, but I'm having a bit of a problem.  All spawners in the game seem to have been replaced with 'limited mob spawners'.  This is fine, except the spawners seem to completely ignore light levels and will spawn monsters even if the entire area is covered in torches!   I'm wanting to use capsules to pick up spawners I find that are interesting and then relocate them into a mob grinder for use, but I'm worried that if I can't turn them on and off using lighting that I'll end up getting too many monsters really quickly.  Is there a configuration file somewhere in the modpack that I can tweak to fix this?
