There's a slight issue on the footprint (at least the one delivered in Altium Format).
The guide pin on the center right is in the footprint as a .71mm round hole with an elongated slot on the mechanical layer. This doesn't match the drawing.
See here:
https://gct.co/files/drawings/usb4160.pdf
In the recommended layout, it shows the guide pin hole on the right elongated. It should be 1.01mm x .71mm instead of .71mm round with the mechanical documentation layer showing the slot.
This probably doesn't matter too much in practice--I'm sure the elongated guide pin hole was just done that way to allow for some manufacturing imperfection, but it's at least not their recommended footprint.

Hello FA1234,
Thank you for waiting while we investigated your feedback.
The exact slot is defined on Mechanical Layer 1 in our Altium files. The round hole you see was added only as a drilling reference for the PCB manufacturer. If you prefer, you can delete the round hole and keep just the slot on the mechanical layer.
When generating your manufacturing data, please make sure to include Mechanical Layer 1 in the Gerbers so the fabricator receives the correct slot definition.
Please don’t hesitate to reach out with any other questions or feedback, we’re happy to help!
Best Regards,

Giving a round drill and pad and marking that it's actually a slot in a documentation layer is confusing to me as a designer and unclear to the fabricator. Contradictory information shouldn't be given, and the drill/slot output will likely be used as-is if the fab isn't really paying attention to this conflict.
In any case, you're welcome to not fix it, but I don't think this meets your typical standard.

Hello FA1234,
Thank you for sharing this feedback. We completely understand your concern about the contradictory drill/slot information. To address this, we’ve updated the library so that it now shows only the slot in the Multi-Layer. This removes the extra round drill reference and ensures that the fabrication data is clear and unambiguous.
We appreciate you pointing this out, it helps us maintain the quality and standards you expect. Please let us know if you notice anything else. We're more than happy to assist.
All the best,
Dizar
