PAH cut off dates?

So somewhere in my TNEW/Tessitura there must be a set up that at a certain number of days prior to an event, we can no longer mail tickets. However I think that somehow is affecting my PAH as well because I'm getting a ton of "hold at box office" (will call) because it appears to be the only option. I WANT people to be able to select PAH but I can't seem to find those "days prior to event" settings. Please advise.

Sorry if I am not explaining this correctly.
