PHP Warning: array_filter() expects parameter 1 to be array, null given

I was just trying out your plug in and exported some fields from a site, then tried to import them via the import tab on the plugin and am getting the following error:

I can confirm that Pull Request #18 works as I have just used that as the plugin and it imported successfully.
