Question: Why does animation "blip"? Two animations in one - are they in sync?

Lett_L_rot_AL_MapleQuestion.mws

If the attached program is run, at the end are two animation outputs.  One is of two letters A; the other of the single second A being animated.   The second letter A animation works fine, but in the former it "blips" on Continuous animation, and on 'single cycle' the A totally disappears.  I'm using the same number of frames, 48, for each. 
   Prior to that is the letter L which is meant to give the illusion of it rotating, and the letters A getting out of the way.

   Any help on ridding the "blip" most appreciated.
