Unable to import Geodirectory settings using Json file

Steps:
1-On one site, configure Geodirectory plugin 2.0.0.83.
(This is List on the top left of the image)
2-Spin up another site (e.g. a development website) with the same Geodirectory version plugin and addons.
(This is Log on the top left of the images)
4-Install “Disable Real MIME Check” plugin onto target site (which is on Log).
3-Export the Geodirectory settings from List.
4-Import the exported file from List to Log site.

Expected Behavior
1-File accepted with no error message

Actual Behavior:
1-“Array( [error] => Sorry, this file type is not permitted for security reasons.)x”
value displayed when file first selected
2-“JSon file is not valid” error is given when Import Data Now is clicked.

Other notes:
CSV upload of categories worked. That is the only one I tried at the time.
