@Ofnuts, KDP is a real can-of-worms
You calculate and down load a template from their site https://kdp.amazon.com/cover-calculator That comes in two forms, a PDF or a png. Obviously the PDF is opened as 300 ppi but the png is a monster 600 ppi.
No wonder the OP's art-work imported at a small size
Then the included text file ends with that CMYK / PDF message. Not the job for Gimp.
Lets see what Jude48 comes up with.
