This is a bug with the instance object of the AGV template. Apparently, that object never got updated to the new stats structure. I'll add a case to the dev list to fix that for the future.
In the meantime, you can update it manually in your model following these steps:
1. Open the AGV Process Flow:

2. Press the Edit Instance Object button:

3. Delete the TaskExecuter in that view and drag a new one in:

4. Delete the AGV in the model and drag a new one in:

Then when you pin the statistics of the new AGV, you won't get that error message about the old stats structure:

You might get an exception about accessing stats. This is a known bug with the State pin button.

You can ignore that error. If you reset the model and close the system console, then it will work fine:

You can also drag a State chart directly into the dashboard rather than using the Pin button, and it will work correctly without an error message:
