Photoshop 2023 Crop Tool not respecting exact sizes using W x H x Resolution

I am quite new to Photoshop and trying to set a preset on the Crop Tool to crop a series of images to the exact same size each time.  The image is an imported page of a pdf document.  I am using a macbook pro.

I have reset the Crop Tool.  When I choose W x H x Resolution from the drop down and choose a width of 3000 px and height 1700 px and resolution 300 ppi the crop box is at a random size that is different.  The width is usually the same as the original width of the Image and the height is some random height that is not what I entered.  I tried clearing with the clear button and still no luck.  I also saved presets at the desired crop size and when I select it again the crop box is not the correct size.  I can see the size by dragging the edges of the box and resizing manually to the correct size but that is tedious.  Am I doing something wrong or is the W x H x Resolution exact size entry broken for crop tool?  My photoshop is up to date.
