data type not changing after JSON

[richcarr2]

If I create a new workspace, download templates and data for hl7, everything is great. If I download files and templates for JSON, everything works fine. However, once I pick a JSON file, I cannot go back to a hl7 file. I get 👍 Conversion Error - Process failed: The input data could not be parsed correctly: Unexpected character encountered while parsing value: M. Path '', line 0, position 0.

The only solution for this is to start over.
