Welcome to our community, stephlyn42
My question back to you would be to ask where exactly you are
inserting the Blank slides?
If you inserted an image on perhaps Slide 4 and configured it
for the project, it only should appear on slides that follow the
image. So if you inserted the Blank slide on perhaps Slide 2, it
won't show there.
If that isn't it, I'm a bit stumped... Rick
