Text teleporting to corner during playback.

Hi there, I'm pretty new to Adobe premiere pro and was trying to make an edit. I have a few different effects on my video right now, and during one of my shots, when i'm on a still frame the text sits in the middle how it's supposed to. However, when i look at the video in playback, it changes size, and teleports to my upper left corner. I used a youtube tutorial on how to add transparent inverted text to my shot, but i think my bug has something to do with the track matte key effect. I am kinda lost here and was wondering if there was any advice on how to fix this. Thanks in advance for any tips.
