Return to the Layer Window and
resume the track process, using the
Track Forward button this time.

Once complete, scrub the CTI to find
any aberrant Tracker Keyframes, then re-center them atop the
feature - be sure to place the Attach Point back in the center of the
Tracker where needed.

Once all the latter Tracks are complete, jump back to frame 25, then run
a Reverse Track to finish the process.
18
Apply the Tracker's data to the Null, then return to the Comp Window
to review the track by scrubbing the CTI - look for any additional bad
tracks that need to be manually adjusted.
From now on, you can simply adjust the Null's position to correct for any
Tracking errors. But once you select the Null layer, the footage becomes
obliterated by countless Tracker Keyframes and its path. Open the
Display
dialog to disable the 'Motion Path'. You can
then resume your manual repair of the bad track and use the Null as a Parent
for whatever element you need to add to the scene.
