Contents changed and lines shifted after copy paste


We have a Problem concerning SPSS: After copying one or several lines in our file to another place in the same file, the lines start to shift and new Content occures (like Show in the Pictures attached). Yes, we do have the newest Version, it happens with every file we have and on every Computer. We also tried to copy the Content into a new file, but the Problem stays the same.

Sometimes we get another error, while saving the file:

"The attempt to save the data file has failed because the disk is full, an I/O error has occurred, the variable dictionary is invalid, or the task was interrupted. IF SAVING OVER AN EXISTING FILE, THAT FILE HAS BEEN LOST."

Has anyone of you experienced the same or know how to fix that Problem? We would be very greatful. Thank you in advance.
