Closed Issue: Remuxing resulted in .ts file instead of .mp4 [1450]

I created the 2 new profiles so that I can remux directly from the .wtv file to h.264 mp4 (I want to direct stream this to my roku with Plex). When using the MP4 Unprocessed profile, the resulting file was a .ts file and not a .mp4 file. I have attached the log from the conversion, please let me know if you need anything else.

Thanks
