Why won't the shaders for landscape layers compile?

I am still just a student so my knowledge of ue4 is limited since I am still trying to learn it, and I’m not sure if this is the right place to ask but I have an issue with painting multiple layers on a landscape. I created a material and added a few layer blends with the help of some youtube tutorials but when I paint other layers on top of the base one, the chunk of the landscape just becomes blank like other objects when waiting for shaders to compile, but in this case, even after the shaders are compiled the landscape is still blank. I tried restarting, making a new landscape, opening every material and texture involved so the shaders would compile again, but it’s no use. How do Ii fix this?

Did you create a layer info file for every layer (the + sign with a dot to the right of the layer listing)?
