There are several reasons why this might occur. Normally the cause is that we have flatten terrain enabled and the path system can't alter the terrain around the path. Check that that is disabled. Flatten terrain is found in the second tab of path tools panel.
Basically what is happening is you are attempting to place the path too close to something else that is controlling terrain.

and why is the path floating?

Could be a one of a few things. If the terrain is being removed when you place the path then most likely tunneling has been enabled. If you are placing the path on a slope, the max angle is 15 degrees from flat. One might also have enabled global vertical snapping in settings.
