Update with the passing bug:
If the skybox is really glitching out then unsub to the mod then re-sub maybe that will fixed the issue with that sorta skybox. (Not the owner of this modpack so i don't know too much!)

If you want more help you gotta to speak with the owner since this is all I know about it.
