Backlogs of finds not in order

[+BlueMoth]

I have been backlogging some benchmarks I found last summer. Even though I looked up the correct dates I was there by my nearby cache finds, logged the benchmarks with the correct dates, and the photos I took with the correct dates, the logs are showing up right in the middle of my recent finds. So if I am putting a date in for last Sept, the logs are showing up right in the middle of April on the finds page. Anyone know how to fix this? It's making me crazy.
