Hi Jon
When you create your import select the post_type that you are trying to import into, for example you mention a test page, i would select "page" from the dropdown. The "acf-field-type" post_type that you mention is a private post_type that acf uses and this is not what you want to import to.
From your attached screenshot it seems that you are trying to import into the repeater field with the key "map_page", onto its sub field with the key "company_name" with the value "Ashley Chicot Electric Coop Inc"
Sorry i am not to sure what you mean by " Are you saying I need to make 360 maps on this page", what is a 360 map?
If you need abit more help can you send me a copy of the csv or a sample of it to understand what data you are trying to import, and a screenshot or export of the acf fields you are trying to import into (you can reply and make the ticket private if you do not want anyone else to see the files/data).
Thanks
james
