wrong word marked - segmentation

[mirjam-amsterdam]

searched for שעהן נעשטאַלט in nybc212765
tried to add a colon (:) at the end of the word זשיטניצקי - it has זשיטניצקיז
when I press the word for correction I get a full stop. This must be the dot at the endof the preceding word.
when I press a bit more to the left, the word הערבּסט, the correction window tells me to correct זשיטניצקיז. Wehn I press עטיוד I can correct the ). So something moved by one position, I assume?
