Since most of the corals positively thrive in this tank, I assume water parameter is not the issue.
Things I know about this coral, it doesn't need high intensity of light and also average flow.
It is quite sensitive when exposed to high intensity of light such as T5HO and MH.
Try moving them as same level as cynarina or even lower at the bottom.
