Starting new motion path when previous one ends doesn't work if first one is a slide trigger

Hi all,

I think I might have discovered a bug, but maybe someone who is in the know can tell me if I'm just doing something wrong.

I have an arrow that has four consecutive motion paths intended to portray a single smooth movement. The second, third, and fourth motion paths each start after the previous motion path completes.  So, as motion path 1 ends, motion path 2 starts. As mp 2 ends, mp3 starts. As mp3 ends, mp4 starts.

At first, I had it set up so that the first motion path started as soon as the arrow appeared ("timeline starts on arrow"), and this worked wonderfully. However, I realized that I needed the arrow to remain stationary for a few seconds before starting on motion path 1. The only way I know to do this is to change motion path 1 from "when the timeline on arrow starts" to "when the [slide] timeline reaches X seconds,." 

The problem is that the first motion path is set as a slide trigger and the subsequent motion paths are set as object triggers, and there seems to be a disconnect between the two. Only motion path 1 is activated. The subsequent motion paths do not kick in as they should. The work around is to convert all of them to slide triggers, kicking in at a certain spot on the slide timeline, but using the "when animation completes" object trigger saves time and reduces the possibility for (mathematical) error, so I would prefer that method.

Please check out the attachments, and thank you in advance for your help! If this is a bug, I can create a ticket.
