SchedulesDirect plugin and CableCard channels

I'm having a bit of an issue getting my HDHomerun Prime channels to be identified by the SchedulesDirect plugin. Here is an example

HDHomerunPrime scan finds "FODHD" and says channel 732

In my schedulesdirect guide I have "FOODHD" and says channel 732

under the plugin I have ticked "allow EPG Channel Mapping by Channel Number only" and ticked "Force full guide update on next TVservice start" (and restarted)

I believe this should get these channels to map - but it doesn't. Some channels...
