Image jumps while adding motion with position and scale

Just downloaded the Premiere Pro 2023 and trying to add some motion to a still image using position and scale but everytime I do, the image jumps in scale and position instead of having a smooth motion throughout the entire clip.  Weird thing is I just tried exporting the clip and export looks fine, but watching the timeline in Premiere is bad.  I've attached video clips to show.  Is this a bug with the system?  I've tried closing out Premiere and rebooted my computer, but still have the same problem.
