This amongst other anomalies has been reported before. So presumably it is a bug. There are quite a few bugs as almost everyone has used Dalvik in the past. No doubt Google will address this in due course. If it is important to you, then make a bug report to the official Google forum. Google does take well documented bug reports seriously.
For the moment, unless someone puzzles out a workaround, is to either live with it. Or revert to Dalvik for now which is what I'd do.
