White boarder flicker on GIF export

[Nepp1]

Hello! I'm new to this program as of a few hours ago. I want to make a simple text animation with a transparent background as an overlay for video. The trouble I run into is this flashing white border thing that keeps showing up in the end of the animation.

This developed after I had learned how to get rid of the white matte that was surrounding the animation and sized up the animation itself to create cleaner lines. I can not find a solution to this problem on the Adobe website and was wondering if anyone has dealt with this and could help me.

that looks like something specific to your fla and appears to be on the last frame(s) of your animation.
