How in the Sam Hill do I apply a Multiband Compressor preset to a submix track?

I have a special Multiband Compressor preset that I like to apply (via the Track Mixer) to a submix track in my final master sequence.

Recently (most likely because of all the infernal upgrading Adobe thinks we like to do), I noticed that my filter had been replaced with the generic "Broadcast" setting.

I have the preset I prefer saved in my Effects Preset folder. But it doesn't appear in the Multiband Compressor dropdown when I add the filter to the submix track. And I can't drag the preset to the filter area of the submix track (duh, now there's a good idea that nobody at Adobeland thought of yet!)

So, how do I do it?
