Player Minimums for Raiding

I have been able to figure out how to set player minimums for 10M raiding in the config and been doing that successfully for a while. I would now like to do playerminimum for 25M as well. Since they share an instance ID, it seems that the configurations step on each other. For example, I tried to put playermin for naxx 10 at 7 and 25M 17......but it seems that it always try to do 17 and confuses the server. Is there something that I am missing? Any help is greatly appreciated.

Start by reproducing the reported Naxxramas 10-player and 25-player configuration with shared instance IDs. Trace the module's player-minimum configuration handling and instance-size lookup to determine why the 25-player value overrides the 10-player value. Done means both minimums are applied independently without confusing the server.
