The Pack (2021-Present) template should be added to his page as he is still part of that group, it was included in Lachlan's page when Preston has collaborated more with the other members from 2021 to present. If you have read and seen the tweets of the members of the pack, no one was removed, though they barely record videos together, all of them are still members of the pack.
Proof that he is still part of the pack:
