that can happen. Are you running both programs using the same book.bin file or
do you have different directories for each copy? Same directory can corrupt the
book.bin file due to learning...
Otherwise, the losses should cause the openings to not be repeated, although it
is possible that your book is small enough that the learning disables every line
and the search finds the same best move at that point in the game...
