Report Model Deployment Problem (DataSource)

I created a new Report Model project and specified folders for both the model and the datasources. For some reason, every time I deploy the model I get an error stating the datasource cannot be found. I've tried changing the project properties to no end. Here's the specific output

Deploying to http://localhost/ReportServer?%2f

Deploying data source '/Data Sources/CRM Database Conection'.

Deploying model 'CRM Filtered View Model'.

The item '/Data Sources/CRM Database Connection' cannot be found.This seems to happen a lot when creating logical joins from tables from different datasources.
