Why are redactions applying to the same spot across multiple pages??

This is so unbelievably frustrating, and it seems to be an issue that has gone on for years and Adobe isn't doing anything about it. I'm trying to redact police reports and for example, if I redact one area on page 5, it will apply the redaction in the same spot on each following page. So now, I just have random redactions all over every page of my PDF. In looking at suggestions in this community and in other places, I've tried to remove the background (although, I always get an error that there is no background), I've converted the PDF to a word document, and then back to a PDF, i've flattened, sanitized, everything. The only thing that works is printing off the PDF and then scanning it back it. This is such a waste of time and resources. There has to be a solution, or surely, Adobe could fix this issue??
