When reading about quantum wavefunctions, I understood that different subshell have different "shapes" of orbitals, which describe the probability density of the electron. The orbital "shape" is derived using schrodinger's wavefunctions. However, I also know that waves are supposed to be periodic disturbances/oscillations, yet there seem to be no repeating "structures" seen in orbitals.

I understand that wavefunctions are used in quantum mechanics and not classical mechanics, but if they are associated with the wave behaviour of the electron, then shouldn't they be like classical waves?

What misconception do I have?
