Prints have unequal borders not shown in Lightroom preview

I have a MAC 10.11.6 withthe El Capitan operating system and an Epson P800 printer. I have been printingsuccessfully 14 x 9/25 images on 13 x 19 paper, with1.75" borders on thetop and bottom and 2.5” on the sides. In the margins box in the print module, Ihave placed all sides at 0.25, cell size 6.50 height and width at 9.50.

 

I recently upgradedLightRoom to the Classic cc version and I now get an image that is 1.25” on topand 2.25” on the bottom. All the dimensions have remained the same in the printmodule. I occasionally get a perfect print in terms of borders, but most of thetime the image is farther up the page (bottom heavy).

 

I hope this makes sense.does this have to do with the new Lightroom trying to work in my old computer?how can I make it do what I want it to and as it was doing before I upgradedthe system?

 

thanks for any help,
