Zbuffer issue with my transparent material

Hello guys! First of all thanks to anyone helping me!

Second: I’ve been working on unreal for a while but I wanted to get my hand on every little corner to at least somewhat understand them and make a game out of it.
First thing first I wanted to do a good debug environment before getting myself wrapped in the actual making of the whole game.
I did some transparent mesh to show explicitly trigger on debug mode while playing a build or something like that.

It worked great but I have a weird issue with the zbuffer where the mesh rendering would get obstructed by a mesh behind it.

Even weirder : it happens only from certain angle of the game camera or the editor camera ( I haven’t tested in a build )

Can anyone help me with this?
