Hello Admin! I'm experiencing a new problem with My Posts (or maybe it's not new but I'm just noticing it

). I always start my day at ECF by going to My Posts to see if there are any new replies in my
threads. Alas, for some reason, not all of the
threads with new replies migrate to the top of page 1, as they always did. I missed several responses to my
recent posts because of that. I never had to look farther back than page 1 or 2 to find all the new posts. Today I found several new posts on page 3 and 4--the titles of the
threads were bolded, indicating unread thread, but the thread didn't move up to page 1.
Again, I'm talking about my most recent posts, 1-2-3 days old, tops. Am I doing something wrong? I checked my general settings, nothing seems to have changed there.
