Packlink generating strange labels and I cannot pay for them?

[laurakaydn]

When trying to purchase a pack link label for all 3 items sold, packlink Is generating a strange label with extra characters and the pay button is greyed out. In comparison, the Royal Mail option is perfect. Any ideas anyone?
