Used Space - Phone Reserved/Common

When I go into Settings-More-Memory-Used Space-Phone Reserved, I notice it says I have 79/150 text messages.  I actually only have 48 messages.

Does anyone know how to clear these out?  Also, in the Used Space-Phone Common, it is showing 168442 KB in Others.  This taking up alot of room.

HELP!!!!!

The total messages is in Conversation View.

I have had this same problem twice now.

The 1st time I "fixed" it was doing a master reset and a master clear.

Now, it has happened again.  I store all my photos/videos/music/etc on my 8gb sd card and my phone memory is full again.  I tried to send a pix message but it wouldn't work because of the whole Phone/Reserved Common Memory being full.  

I really don't want to do another master reset/master clear, as I'd have to change all my settings back to the way I like them.  This seems to be a common problem but I haven't seen any definite solutions, I've searched for hours on the subject tbh.

I have deleted the following and have had no change in my "free" memory:
- Call History
- All texts (inbox, outbox, drafts)
- Recent web pages
- Cache for the browser
- Cookies for the browser

I don't have any applications or games installed.  I do browse the internet quite frequently on my phone, I'm wondering if that's how the phone common memory gets full?

Has anyone figured out how to free up the common phone memory without master reset/master clear?

Here's some screenshots of my phone's memory:
