Using ExtensionDevelopmentTools-21.1.0 - I have deployed and activated an extension, but when I make some edits and re-deploy I get prompted for information as if its a new extension (Vendor, Name, etc), but then it errors out because the extension already exists. For some reason the initial code is not finding the extension in NS. I have checked the manifest in the backend and nothing seems amiss. Anyone have this issue or know where to troubleshoot
