Second tap PlayNarration kills highlighting

I have two narrations on a page. Narration 1 runs onPageLoad Tap element A and it StopsNarration 1, hides it, shows Narration 2, PlayNarration 2. Chained actions screenshot below. There is a condition on PlayNarration checking an app counter. I don't think it's related to the issue.

All is fine if I let the narrations run their course. But the following scenarios kill highlighting on Narration 2:

1. I tap element A while narration 1 is still going, it stops Narration 1 and hides it as expected. BUT narration 2's highlighting cuts out after just a few words. This happened a few times then stopped :/
2. I let Narration 1 play out, then tap elem. A starting Narration 2. I tap elem. A again while Narration 2 is running. It continues the audio, but cuts out the highlighting. Now whenever I tap elem. A I no longer get audio or highlighting! This is consistent.
