I've got some Euro locks on external doors, but people keep locking them
and leaving the key on the inside. This means I can't put a key fully in
from the outside to unlock it.

Is this a bug or a feature?

Feature.

This can be changed by a locksmith in the more expensive cylinders, i.e. Kaba,
Keso etc.

Mine are Ultion 3-star (£45 retail each, apparently)
