Importing doesn't work!

Hi!

I exported nodes from a content type of mine (using importexportapi) to a XML file. Right after, I tried to import that file using importexportapi as well, but nothing happened. Doing that, I thought some primary key error could be happening, so I deleted all my nodes from that content type and tried to import the XML file again. Nothing was imported

I didn't change any mapping (when exporting and importing), so I should import my file normally. I tried to read the documentation, but nothing helped me.

Is there something I'm doing wrong? Shouldn't that work perfectly?

Thanks for your help! A lot!!

Best regards,

Rodrigo
