You may notice several differences between the UPS labels produced by Shiptheory and UPS labels you create manually through the UPS.com website. The UPS system that Shiptheory communicates with to produce UPS labels arranges label content intentionally differently.
The font face, arrangement and spacing of certain elements on the labels provided by the UPS API may differ from labels provided by the UPS.com website. Both labels are valid and certified UPS labels.
This is nothing to worry about and will not cause any disruption to delivery.
