Translucent Tree Material Shows Objects Behind it

So I’ve been working with LODs for this large-scale forest I’m designing in the engine and after placing more than 400 trees I started to notice a unusual effect where the trees in the background are ghosting through the seemingly transparent trees in the front. I’ve attached screenshots of the tree material and the ghosting effect, please comment if you need any more info or screenshots, any help would be appreciated.

I won’t copy the docs here.
Shortly - depth sorting is a expensive process, you better avoid it when possible. For trees you may use masked transparency.
