Issue:

The spell ranks Desperate Prayer do not group together in the spell book as other spells do.

Expected Behavior:

Spell should group all ranks together like the other spells do.

Reproduction:

Have an Alliance Dwarf/Human Priest with multiple ranks of Desperate Prayer learned, open spell book.

Are that all different ranks?
Can you post 2-3 spell ids?

Yes those are all different ranks, you can see them all here (except rank one since that is the page its on and it is showing "related spells")

Pretty sure they are:

13908 - Rank 1
19236 - Rank 2
19238 - Rank 3
19240 - Rank 4
19241 - Rank 5
19242 - Rank 6
19243 - Rank 7
