It is possible that you have encountered a small, but known, bug in the CDU. Using you picture with the CDU as a reference, I would:
1) Select the LSK L3 (CF25R) and paste it in LSK L2 (where ANT is).
2) DO NOT press EXEC, but press LSK L6 where you will see ERASE.
Doing this will, set all the altitudes to where they are much more reasonable.

That's really a slick way of solving that problem and getting a T/D. Maybe on 15-20% of my flights I would not get a T/D. Right now I am flying from KJFK to KDEN. The plan originally dumped me on the ILS couese for 35R at FL360 at 300 KIAS. I got rid of that issue in 30 seconds using the above method. I used to get a T/D by by deleting 1-4 of the last waypoints and executing, then adding them back in and executing again. Maybe it worked maybe it didn't. Maybe I only needed to get rid of two and add a new waypoint. Or maybe I had done it in the wrong sequence. It could take half of the flight just trying to ger a T/D out of the FMC. I have used your method foir times now and it works great.
