Elevator buttons disapearing depending on the angle of the camera

[RealRandomes]

So, if im looking directly at the buttons they appear as normal, but if i look away just a little bit they disapear, it's not a big deal but it's a bit uggly to look at, im using other mods but it's been weeks since im using them with this mod and only today this started happening. My Minecraft version is 1.12.2
