I had this same problem with 2012 Carlson and I never did resolve it, but now it happens in my 2014.
New drawing, nothing special, but the program randomly will change the angle format from Surveyors Units to Radians. Frequently when I switch back to DMS the precision is degrading to minutes instead od seconds which is my usual setting. This does happen between multiple drawings, not just one.
This is a random act, and I cannot find a common command or action that precipitates it.
Any clues?
Thanks,

Happens in Carlson 2015 Civil/Survey as well. Not very often, but every once in awhile I do not get the expected result when I am rotating objects.
Fairly rare occurrence.
Happens in Carlson Survey CES 1997-2001
Also happens or notice when rotate something and the result is obtuse to where it should be
