The House Deneith Heir background help please

I take  House Deneith Heir as a background (giving me mark of the sentinal...seems op). Can I then take potent draonmark as a feat later to always have the spells ready? I added it to a toon and it seems to not give the spells just the Sentinal/shield perks?

Yes, you can, though how much use you get out of that will depend on what class you choose.

Are you saying that the Spells of the Mark from Mark of Sentinel are not showing up as always prepared even with Potent Dragonmark? If so, then that's a bug.
