Motion Tracking and Freeze Frame not working when exported

Hello! I created a video with motion tracking and Freeze Frame. For the Motion Tracking, I had to adjust and add a lot of keyframes to make it look like a box is following the subject of my video.  I did this several times as I had a lot of objects that I needed to track (6 total). I also added the Freeze Frame function three times during my video to pause my video right when a new motion tracking box appeared on the screen (So I can later add text). It all looks perfect when I am in project mode, but when I export it (I have tried both MP4 and MOV) the video will show the tracking perfectly, then it will freeze frame (Which is EXACTLY what I want it to do) but as soon as the freeze frame is over, the tracking boxes I created are WAY off of the subject they are supposed to be following. Any advice? I am VERY new to Premiere Elements, so please answer without a lot of "lingo" if possible.  THANKS!
