Photoshop: Print Preview keeps resetting position of document

I have Photoshop CC 2018. When I go to print something that is smaller than the page I'm printing it on, I often change the location of the item from being centered to somewhere else on the page. If I then change the print media (for example, from plain paper to premium presentation paper matte), the item gets recentered in the print preview. This has only started happening recently. I used to be able to specify where on the page I wanted something to print, and it would save that setting. No longer! I don't want to keep having to remember measurements where I placed an element to print on a larger size paper (e.g. a 4x6" photo on a letter size paper). Please fix this asap!
