Apart from the expiration date issue, the British unilaterally extended their territory taking more land than they were assigned by the Utrecht treaty, several times. Sometimes using such scummy techniques as asking the Spanish government for permission to temporarily built sick houses outside their border during a cholera outbreak, and when the outbreak was over... they just kept that territory. To be honest, I'm not a patriot by any means and I do think that Ceuta and Melilla will probably need to be handed to Morocco at some point, as enclaves in general don't make much sense. But the situation is not even remotely comparable from a legal and historical standpoint. I don't think the differences can even be called "subtle".
