I sent over a file with a bug report.
It's included with Issue report #17127 — Incorrect pronunciation of "GIF". 
What are you trying to do with the different export method? Is it to save space? I noticed that the file export was ~24 MB. I dropped it on ImageOptim and it was a little over 5 MB. Maybe that's a better technique, if you're looking to reduce file sizes?
Although, the GIF didn't look very good. I tried both methods. I also tried making an animated PNG, but the quality was not so good. Animated PNG is still new tech... apparently bleeding edge tech.
