I had one coconut tree yesterday near a cliff. I shook it and one coconut fell and disappeared into the ground. I think it is a bug. Try moving your tree to another location.
Can you post a screenshot? It sounds to me like there are no suitable drop locations near the tree, so the game is not releasing them. But a screenshot of the tree would be helpful.

Yeah, this is what I was trying to say as well. It does disappear on weeds but I'm wondering if there is something blocking the fruit on all sides so the tree just isn't allowing it to fall.
