Why do some messages come in as "SMS/MMS" and others simply arrive in "All Messages"?

Seems to me that "all messages" would include texts from any source, and multi-media messages as well.  My filter allows some to come through and show up in BOTH folders.....other messages (text, and text with pictures) don't show up unless I bounce between folders.

What gives?  I didn't see any default to pull all messages into the same folder.... 

Note: some threads with SMS will include MMS messages, and deliver just fine.  I didn't see anything in the settings that addresses this question.  Odd.

Any wisdom would be appreciated!

I have found the same problem, and I find that it only happens with texts coming in from iPhones......  Go figure

That's because, when iPhone users send messages to multiple recipients, they get sent as MMS.
