Tristian cannot learn Burning Hands EXCEPT in his domain slot?

[Godwin]

The other domain spells CAN be learned in other slots.

This bug is annoying, I wanted to give Tristian 2 Burning Hands spells..

That is WAD. Burning hands is an arcane spell, which can be learned by arcane casters (wizard, sorcerer, magus, bard.) Tristian gets access to it because of his clerical domain, which allows him to prepare certain spells based on his deity in a special domain spell slot. If you would like him to serve as more of an offensive caster, consider giving him some ranks in wizard, or the sorcerer subclass that scales off of wisdom and then making him a mystic theurge.

But his other domain spells (the ones in dark brown outline) can be used in all slots.. man it's very weird..

Also, the only domain he has listed above in his spellbook (and in his char info), is the Good domain.

The other spells are likely all cleric spells, that he can cast anyway (domain spells can potentially come from any class's spell list, but if they aren't a cleric spell they can only be memorized in the domain slot).

The other thing is because of Tristian's archetype, which basically trades his armor proficiency and second domain power for the ability to cast spells from ALL of his god's domains. So he only gets the good domain power, but has 5ish domain spells to choose from at every level (I think he might also be able to choose one of the other powers every day, but I'm not sure - haven't used him much).

Hm that's interesting, okay, this wasn't clear at all.
Didn't even know Burning Hands was wizard-only spell.
Thank you.

The real bug is that he's missing the label that his second domain is fire and the fire domain powers and there doesn't seem to be a way to change the domain his extra spells come from as his archetype gets. (Note I'm guessing how his archetype is supposed to work based on this but they've changed stuff enough that it's hard to know what is a bug and what is a change https://www.d20pfsrd.com/classes/core-classes/cleric/archetypes/paizo-cleric-archetypes/ecclesitheurge/ )
