Simple trigger not working

I set up a channel trigger to send a message three days before check-in, and it doesn't appear to be working for my last couple of Airbnb guests. I've double checked everything and it all appears to be set up correctly. (I just recently started using OwnerRez so it's never worked before.)

I have a channel template created and the trigger is enabled with the channel template selected. 

All the options are pretty much default so it's not doing anything fancy, but I don't know why it's not working. 

oddly enough, it looks like the trigger just fired. 

i wonder if this has anything to do with a bug in hospitable? i was testing hospitable prior to ownerrez and had set up a few scheduled message. one was similar to the one i posted about (three days before check-in). however, i deleted my airbnb connection in hospitable when i decided to go with ownerrez. i thought ownerrez was firing properly with my last couple of reservations but just realized today those messages were actually coming from hospitable (even though i had disconnected airbnb from it and couldn't even access the scheduled messages section). 

as soon as i disabled those scheduled messages, it appears to have unblocked ownerrez and allowed it to send scheduled messages. 

curious if this is the reason? if it is, why was the hospitable message sent but not the ownerrez version? and is there a way to send a notification if a trigger doesn't send for an unknown reason?
