Poor printing quality

Ordered the pack of 50 bubble mailers. Although the mailers were good quality, the printing was not. There is a huge white line that goes through the middle of each mailer (right through the middle of my logo). Every single mailer is printed this way. So annoyed because this is the second time I’ve had print issues with Sticker Mule. Last time it was a tshirt that has white residue and did not wash out after multiple attempts. Now a whole pack of bubble mailers that aren’t up to standards. I won’t be using these to ship out to my customers because it looks sloppy. I wish I had an option to post a picture here.
