Flying movement blocked

Im unable to move around during flight which im not sure why, i am setting the max fly speed which ive shown here, any suggestions as to whats wrong?

You say flight, but you have swim stuff…

What about collisions with the water or similar?

So im using a flight system underwater instead of a swim since i need the character to float up like buoyancy. however there was a video of a guy with the exact swimming thing i needed but there isnt a tutorial on it.

If anyone knows how to replicate this please link me the vid.
