I have just checked your problem and it is not a bug.
In Black Ink I resize my picture and save it

When I go (for example) in Photoshop, my picture have a good pixel dimensions, but my print size is larger (281x352cm) due to 72dpi.

I change my Resolution in 300 dpi, due to the Document size, Pixel Dimensions need to be changed

So I change my pixel dimensions and it's alright

Maybe there is a solution to keep all print size information between different softwares, but we need to study this case.
I hope it will help you
