Divine smite multiple times

So I'm making a paladin for the first time for CoS, I haven't started yet but I put him up to level 3 just to see the different oaths, forgot to put it back and when I checked the character sheet for something else I noticed it was there 3 times in my spell list, now I have it learned at level 1 but wondering what the other 2 are, is this just a glitch?

Ahh checked there and that's what's going on, thanks for that mate!

What was the cause of this? I am having the same issue but the reply telling you the cause isn't showing for me.

The reply was mine, and it's not there anymore because it got spam-flagged by mistake. Unfortunately I wrote that two years ago and I don't remember exactly what it said.

The spell should be there twice — once for your once-per-long-rest free casting of the spell, and once for casting it using a spell slot. I don't immediately remember why it would be there a third time, but if you set the character's privacy setting to Public and post a link to it here, I can take a look and see if it jogs my memory.

Oh wow thank you for replying so fast! It is only there twice, but I thought that was a mistake - it's my first Paladin, so I wasn't sure. Thanks so much for clarifying :) much appreciated!

No problem!

You'll see this behavior any time you have a feature that gives you the ability to cast a spell without a spell slot (usually a specific number of times per long rest) while also letting you cast it with spell slots. Feats like Magic Initiate, Fey-Touched, etc. will do the same thing with their spells, as will species like Elves and Tieflings that grant spells like that.
