Having issues getting video/timeline to pause using triggers

First, some background. I created several interactive videos using Camtasia. They are software walkthroughs with hotspots at key points that viewers click to continue the video. I rendered them as SCORM files and uploaded them to my LMS. Users don't like the navigation through the different modules in the LMS, so I am recreating everything in Storyline 360 so it can all be self-contained. To start I simply rendered the video as a normal mp4 video from Camtasia and imported it into a Storyline 360 project as a video on a slide. I added my first hotspot and created a trigger to pause the video when the timeline ends on the hotspot. I created another trigger to play the video when the user clicked the hotspot. It worked perfectly. I moved on and created the next hotspot and set up the same triggers. This time, each time I previewed it, the video paused too early and cut off the audio. I went back to the timeline and confirmed I had the hotspot lined up exactly where it needed to be, but it still paused too early. So I started digging in this forum and found a post that said rather than pausing the video, I should pause the time line. So I edited my triggers to pause the timeline rather than the video. Again, the first hotspot worked flawlessly, but when I got to the second one, nothing paused and the video blew right past the hotspot despite not clicking it. So I dug some more and found I can just set a trigger to pause the timeline at a specific point and not use the trigger at all. Still didn't pause. I then tried adding a cue point and pausing there. Still not pausing. The first instance works, but the second one just blows on by. What am I doing wrong? This seems like it should be such a straightforward issue.

I attached my .story file. This is the last set up where I have it set to pause at the cue point.
