The discussion behind this links talks about the fact that a system can have only one default gateway, there can be only one gateway statement in the interfaces file(s).
As you show us the config for one file in the interfaces.d/ directory, can we assume you have another interface that is up and running for which there is a separate file in interfaces.d/ ?
That file might then not even have a gateway statement if it used dhcp.
