Compiling Shaders over again every time on launch

For a while now, we’ve been noticing that, whenever we launch our .uproject, the Editor has to Compile a rather large amount of Shaders again. I’m not exactly sure since when this started happening, but I’m pretty sure that in the past, the engine was capable of caching the compiled shaders somewhere, and would not require re-compiling them every time the editor was booted up again.

Is there a setting somewhere that can be changed to fix this? Or is my memory simply bad and has the editor always required to re-compile shaders when the project/editor is relaunched?
