With the Standard Single Target build, the addon suggests to cast haunt, but anything outside of haunt then goes completely blank in the boxes. No matter what build I change to it comes up blank after the initial spell. Destro and Demo both still work fine though.

What is the standard single target build?

Deathbolt, Siphon Life, Phantom Singularity, Haunt, and Dark Soul: Misery

Yeah same for me for ages had to go to another rotation helper on only my warlock.
