What you were expecting to happen, and what actually happened:
No calendar has unfilled days at the end of its first week, or at the beginning of its last. Somehow the icon got flipped around a vertical line.
How often does this happen? When did it begin happening?
Not sure when it began happening, but the icon hasn’t changed for me since I noticed the problem earlier.
Severity of bug
Extremely minor. But hopefully also extremely quick to resolve.
