Hi, Did not respect to level off and busted altitude at AFIVA wpt, speed was OK but instead of leveling off at 8000 FT it did climb to 10K

If you look at your first picture, there's an altitude missing on one of your waypoints, which usually means either there's a cost index/speed that makes the profile impossible to fly, or your PERF INIT isn't fully filled out/ improperly filled out.

LNAV: Yes LNAV it's broken, and it shouldn't fly directly to a waypoint if it's not on an intercept.

Your last report about 2500B... that's perfectly fine / normal / legal. At least your VNAV path vector shows you're a little off like it's supposed to. Jets in real life often cross +/- 100 that's totally expected while doing a descent and a complicated turn.
