Hello @MaggyH ,
It might have just been a delay because I'm looking at your account now and all your done posts have some level of impressions and engagement. That said, when I first looked at the campaigns screen for your account several said 0 and 0, but then when I clicked on one and returned to the campaigns screen, they all showed their impressions and engagement numbers.
It may be a weird caching error that requires a clear, or it may just be a minor glitch. I've gone ahead and reported it in case we see more issues like this come up, but I can confirm that your posts are reporting impressions and engagement.
