I have DLed this plugin for evaluation. Persons at my company had configured some small dummy data but I took the example JSON data from the Import/Export area and Imported it into the plugin.
Now I have an issue where the "Inventories Report" area shows only the old form of the original dummy data and not the new forms from the sample JSON data.
I also tried adding a new report to see if it would get recognized but there was no change.
Your problem is not clear. Could you please clarify?
