I'm quite familiar with both issues and probably contributed to them back in the early TGC 2019 days. The rough splines I do may look like your example, but that is because there is actual (cart path / natural area) that causes the shape. 

The inside the fairway bunker lollipop is a longstanding TGC 2019 problem. There are better ways to handle that for the game, but I think many people that are just creating their home course probably still use that method. 

I may still create a fairway lollipop occasionally from doing my long single splines when there are vast bunker / waste area complexes and then forget to go back and fix it. If you come across one of mine, send me a message and I'll fix it.
