SSMA for Oracle - have to reenter password

Hello,

I am using SSMA for Oracle and am prompted to the passwords for each connection when I select "migrate data," even after establishing the connection when I first open the project. I have converted all the schemas already and am just migrating data now. An example of the steps I take can be found below:

1. Open Project
2. Connect to Oracle
3. Connect to SQL Server
4. Do work / configuration for schema(s)
5. Select schema 
6. Select "Migrate Data"

After I select Migrate Data the window to enter the password for oracle pops up, and after I enter that, the window to enter the password for SQL Server pops up. Only after I enter those will it migrate the data.

Does anyone know why this is happening? The documentation says that the connection should stay alive until the project is closed or I choose to disconnect.
