Hi,
Thanks for using our plugin and reaching out to us. I believe that is being caused by a restriction in your PHP configuration. It is called the max_input_vars setting.

You should higher that if you want to use more custom fields.
Unfortunately there is no import feature available within our plugin.
It’s very bad.

And there is no option to reorder the fields. If we confuse the order or forget some fields, we should create the feed and its fields from the start. It’s very difficult for the feeds who had many columns.
