For what it's worth, I saw the same problem on my last (single) log. Here is some background on my setup/situation:
- I don't use Kai Team's post log macro, but one very similar to it
- I had logged my previous 50 finds from my work laptop and imported my databases (but not my settings) back onto my desktop
- I then logged a single find from my desktop, I had no %count variable in my log, so I don't know whether that number was right or not, but the count stored in my custom field using PublishTags("%count") in my post log macro was one too low
- I thought it might be something transient and didn't follow up on it, until reading this thread. Then I went back, added a random cache to the publish log dialog, added %count to the log text and switched to "preview". That showed the correct number.
- when I next log finds, I'll pay some attention to what happens and get back to this thread with my findings
