Why does my permanent accusnap settings keep disappearing with each click?

I've been having a problem with accusnap over the last few days.  when I use a tool (seems like any tool) and enter a data click or anything on my keyboard, my standard accusnap setting is removed, along with any temp setting.  Nothing is highlighted, and the setting seems to revert to a "nearest" snap as the default.  If I go and reset the snap setting, say double clicking on intersection snaps, the next data click or tool selection will remove that selection from the accusnap menu.  

My current work around is to reset my accusnap setting every time I need it, as it is effectively acting as if there is only temp settings, no "standard" settings.

I've been able to reset it a couple times by switching between tools, or setting the accusnap then switching tools, disabling accusnap entirely then renabling, or some combination of those.  I haven't been able to figure out what exactly causes it to get fixed.

I also can't figure out what causes the settings to go away in the first place.

I'm going to try and screen capture a video next time I'm in the office, but I was curious if anyone has had this problem.

Thanks in advance for your help!
