MD5/SHA1 hash not matching from EZ Hasher and FTK Imager

I'm still trying to grasp digital forensics but I understand that hashes are not supposed to change unless you modified a file a tiny bit. I used FTK imager to practice imaging a USB stick and I used EZ Hasher her to confirm if the hash matches the verify hash but does not match. Is there supposed to be a difference between this acquisition hash and if you run the same file through EZ Hasher?

Edit : Thank you to …
