HDV NTSC 1080 30p isn't rendering entire Zone nor Project?

Hey everyone, I have been working video editing lately using Kdenlive v4.8.5 running on Lubuntu v12.04 64bit.
The final rendering looks beautiful, though only about 95% of the entire video that I want rendered is actually encoded.
I tried to render the video by choosing "Entire Project" and "Zone Selection".
I made sure that the "Zone Start" and "Zone Stop" handles were placed in the correct positions on the timeline.
Yet only about 95% of the project has been rendered... and it's consistent, even when choosing a different "Render Profile/Codec".

I had never had this issue before, what can it be that's cutting the end of my video off from being encoded?
