Thanks for the replies folks.
One TB issue resolved itself. I suspect the person was traveling and didn't log the TB in for a day or so.
The other TB I "grabbed" from the geocacher owner (a newbie), "dropped" it into the cache where I found it, "retrieved" it and then just dropped it off at another cache so the owners can track it. I suspect that they didn't realize how to log the TB.
