Hi! 

As per a few other posts I've seen, I'm trying to add a subclass to fighter that essentially gets a few spells as he levels up for reasons. And for some reason, I cannot get the spells to actually show up in the spell list. Now I've added the spells through a class feature (And they show up in there) but they aren't actually adding either of the two spells I've added to the spell list itself.

I've seen a few of these posts and all the answers have been that you need to add a class feature called "Spellcasting". Well, I did exactly that, even added the spells to the expanded spell list on that class feature. But it still isn't adding the spells or the ability to add them to the character sheet.

What am I doing wrong?

Are you trying to give it spell slots and everything like the Eldritch Knight? If so, the easiest thing would be to use the Eldritch Knight as a template for your homebrewed subclass and just add the spells under “additional specific spells,” not on any glass feature, but under Basic Information for the whole subclass.
