Animate title mask from location a to b in Adobe Premiere CC 2017
You need to use keyframes instead of tracking. You can find them here:

For better understanding of how they work, read about them, or watch the video.
Long story short, you need to create keyframe in the first place, where motion starts. After that you need to have keyframe in every place, where is key place of position. If you will just move the mask, after creating first keyframe, other ones will be created automaticly, after you move mask.

To create keyframe, press on the middle round button, in the place highlighted on screenshot above.
