Sage too-frequent updates from SchedulesDirect EPG

Sage (currently 9.2.13) is making EPG update requests to SchedulesDirect every couple of hours. Not too long ago Sage wasn't doing it this often -- more commonly once a day, which seemed to be often enough. Setting an hour (e.g. 3am) in the GUI ara is pretty much ignored so I *don't* have that set.

Doing EPG updates from SD every two hours isn't "hurting" anything, but given recent issues that made SD ban Sage access (until we did a Sage update, then begged forgiveness one by one...) I'd rather not have it doing EPG updates more often than needed. And I don't understand why it's doing an EPG update every 2hrs+ when it used do it every 24hrs.

Is there an issue with the program that needs to be fixed?
Is there a setting we can tweak to control how often (and even when, since the GUI setting doesn't work) EPG updates happen?
