How are you specifying the packet size and what layer does the size refer
to? Perhaps it refers to payload of the ICMP/IP packet.

Generic IP adds 20 bytes for the IP header.

ICMP adds 8 bytes.

MPLS adds some bytes.

The serial data-link-layer adds some bytes.

You are probably beyond 1512 at this point.
