OK, here's the deal, the default constraint was never being added the first time because of a bug. Then, when you re-deployed the package, it tried to add the default constraint, but we explicitly specified the constraint's name as the name of the field (rather than letting SMO create the name for us, like DF_{tablename}_{fieldname}, and the way you named your primary key, it was pk_{tablename}, which just happens to be the same name as the primary key constraint. So, it wouldn't add both constraints.
So, I fixed it so that you can set the default value now on a PK (so it will be deployed the first time) and I fixed it so that when it re-deploys, it doesn't explicitly specify the name for the constraint. Here are the DLLs that you'll need. The only change was made to DBEngine, but the others are the same version and it might need the updated assembly meta-data. The databasedtk.exe didn't change (all of the deployment is in DBEngine).
Just copy these to your C:\Program Files\Common Files\MicroFour\StrataFrame\ folder and then drag them into the C:\Windows\Assembly folder and you should be good to go.
