Having issues Acrobat DC - images disappear and hard to align text fields

Hi there,

I've been using Acrobat DC for creating templates for the past few months. It's been working fine but I've been facing a couple of issues recently:

1. The background image would disappear as I create the text fields on the template. I've tried reducing the image file and had no luck.

2. It's quite difficult to position or move the text field boxes. It would move about 5mm each time when I use the arrow keys on my keyboard. It used to move 1mm at a time previously which was easier to position. And when I move multiple boxes together they would all move at different amounts (some 5mm, 3mm etc) creating an uneven spacing between them.

I'm not sure if I've accidentally checked something allowing it to move by a greater amount. I have to manually reposition it using the field properties one at a time which is so time consuming. Am not sure how to bring it back to the previous settings?

Please let me know if anyone can help me out here.

Thank you
