I noticed the same issues with logging TBs today (hi MaxB!)
When entering the tracking number or reference number I get the correct TB info (name, owner, picture, goal, current position) but the logs listed below are for a different TB--it seems to be the same "different" TB each time you search for the TB or refresh the TB page...maybe a search error in the database??
When I log TBs as picked up everything looks normal: the current location on the TB pages lists them as being in my hands, the TBs are in my inventory on my profile page, the picked up line in my daily activity log shows the correct TB name and pick up location. Additionally, when I click on the TB name on my profile page, I am routed to the CORRECT TB page with all of the CORRECT LOGS. If I then search for the same TB by tracking number/reference number I get the same wrong logs on the TB page as I did before. Again, I think this must be an error in the search function for TBs.
I hope that makes sense...
edited to add reference number for one of the TBs I was looking at today: TB33XD7
