In Photoshop open Path panel and check for paths. Check if there is a Clipping path.
Another way, in InDesign:
Object -> Clipping Path -> Options
Choose None in Type drop-down menu
Well, deleting the path in Photoshop is not the best idea, you now can't for example create Wrap around an object shape and add effects to the shape instead of whole rectangle. To turn off the clipping path in Options dialogue is more flexible.
The difference is caused by Import options. If you turn on Show Import Options mark, you will see the option "Apply Photoshop clipping path". Generally it's turned on. If you turn it off once, it will be off until you change your decision.
Thank you, that solved it. I appreciate you taking the time to help me out.
