Duncanopsammia axifuga Disease, brown jelly

[Aqua Splendor]

Hello, so I'm having a disease on my Duncan, I'm not sure what to do.
I've done a bath of Two Little fishies ReVive, and a bath of Iodine Kent Marine.

They are the only lps affected, at this point I considered them gone but I just leave them for curiosity reasons.
History: I frag them from another tank, put them in this frag tank, they were fine, loved to eat, growing, and suddenly brown jelly disease appeared, started to spread to each other.

An observation: Only one of them went full skeleton gone, including tiny skin and not just polyp
