Why does Firefox sometimes still tell me that I have cache to clear in the Advanced tab of the Options menu after I completely clear it using Clear Recent History?

I always have the time range in the Clear Recent History window set to "Everything", too.

You can see the current cache usage on the about:cache and in "Tools > Options > Advanced > Network > Offline Storage".

While I didn't know about the about:cache page, it doesn't help me understand why Firefox is doing this, and how to fix it. Also, as I said in my question, I already knew about the cache information in the Advanced tab of the Options menu. I was trying to imply that I sometimes have to clear it using both the Clear Recent History feature and in the Advanced tab of the Options menu, because using Clear Recent History doesn't delete it all.
