Logic Analyzer: units swapped in signal cursor pop-up box?

Logic Analyzer: units swapped in signal cursor pop-up box?

tracing a boolean toggling every 25usec (i.e. with 40KHz frequency) : the Logic Analyzer Window displays as follows (see circled data, reffered to cursor position)

Something wrong in what am i doing? 

thanks a lot
