Adding a constraint with Team Coding will modify the TABLE but will not create a new constraint in VCS

Hello,

I am using Toad 12.9 with Team Coding.  If I create a new constraint, the parent table will require a check out and the constraint object will get added to the .TBL file in source control, but the constraint will not be added to Team Coding and no new constraint will be added into the VCS (git in my case).

Is this behaving normally?  

If a Team Coding change is made, it will search for objects to add into Team Coding and the new constraint will be added at the time, but will not be added into Git.

Does this seem like a bug?
