There is also an offset in the position of the asteroid relative to the star.
It is not clear whether this is due to error in the asteroid position or the star position.

Anyway, the offset is dRA=+0.639", dDEC=0.137"

The errors in dRA, dDEC are +- 0.002 arcsec.

This means that you have to shift the position of the star (as given in Preston's occultation page) by these amounts to make them fit both observations.

The fit also means that Kapetanakis should have seen either a 4 or 5 second occultation.
