KickSat decayed on May 15th, so there are probably issues with the calculations (resulting in negative altitudes for example) that cause the error.

Nick,
If you look at the 4th group of numbers in the first line (starts with .1023) and compare it to the same group of numbers in a list of tle data for several sats you will notice that even though .1023... is a small number it is much larger than for the other sats. This value gets large as the sat decays and the drag increases. Be very wary of tle data with a large number in that position. Not a rigerous mathematical answer but handy to know.
