Was about to report the error. It's happening here too. Apparently, what happens is atres downloads the .ts's files, does the first ffmpeg pass to paste them together (producing a working mp4 when its done) then after that, creates another ffmpeg process to make a .ts file (which is always bigger than the already working mp4 file, by several hundred MBs, which doesn't make sense) and then a3w just decides to scrap and delete everything. Pretty frustrating. The only difference I could find was the finished bigger .ts file has captions included (which I could care less about)

A temp workaround I found was to terminate a3w.exe right while ffmpeg is doing it's first pass.
Hope you can look into this denobis, program is pretty unusable like this.
