Organization of spells in NPC Stat Blocks 5e

[MartianXi]

Running a 5e campaign and I'm intending on slightly remapping Halastar Blackcloak as my final big bad, using DOTMM.

I'm finding it challenging to swap out spells within the NPC stat block however, and maybe it's just my OCD but I can't consistently place a spell description from the spells list anywhere in the stat block I choose. By default the new spell appears at the bottom of the stat block spells list, so if I want to swap out a cantrip the new spell appears at the bottom of the list and not with the other cantrips.

If I want to swap out a spell and keep them sorted by spell level, Is the only option to remove every spell listing in the spells tab and add them all back in manually in sequence? Or am I missing something?

Good Day MartianX :)
I believe you need to delete all the spell descriptions from the NPC sheet then reparse the spells or add to the CT. :)

As Bonkon says if you edit the spells of an existing spellcasting NPC you need to delete the spells in the spell section of the NPC and then refresh the spells to have them populate correctly.
