Deleting row in Table Editor: not implemented by SQLite JDBC driver

Loving my trial of pycharm right now. I can see a lot of hard work went into the development. It's the best python editor out there (and I've tested most if not all of them!)

Question: Why am I receiving this error: "not implemented by SQLite JDBC driver" when I try to delete a record in the Table Editor?

I'm connected to the sqlite database, I've tried the Zentus and Xerial drivers, and neither will allow me to delete a record.

I've also tried setting OPEN_MODE to 2 to allow read/write.
