Bug with APPR

Hey guys, hope you’re all having a good time flying the 737 MAX!
As I was approaching EFKT with the TUI 737 MAX, I had APPR engaged and all of a sudden it disengaged itself and the nose of the plane shot up.
Has anyone else got this issue? I’m pretty sure this would be a bug that happens in other planes.
