Are you seeing the data come through on the other side (inside Google's reporting)?
Typically, the network tab of your browser is the most accurate tool to use when determining if a tag is being sent. Many of the browser plugins are watching for the tag to be sent a certain way. If you deploy the tag outside the normal method, the browser plugin can't see the tag. I can only assume Google wasn't planning on you deploying your tag through our Tag Management solution.
