Why isn't the monitor section up to date?

Why isn't the monitor section up to date?

I recently started using Zoho for my business instagram and Facebook. I added a few pages to the monitor section, the "page mentions section" to see when my page is mentioned and the Facebook for a festival we will be at. However, neither of these pages are up to date. In the monitor section for the festival Facebook, there are many posts that are missing, including one where I am mentioned. I was wondering why this might be happening? Does zoho not include all posts in Monitor or is there a problem? Thanks!
