Cache decreases for unknown reason

My cache decreases significantly to almost zero. What could be possible causes ?

As per my memory, I added the last page rule for most urls (domain/*) to cache everything couple days before the sudden decrease. There are some exception rules for dynamic pages that are still either bypass or standard. I tested the rules with corresponding urls and they seems to work correctly.

Do you have any ideas ?
