Self add support in slicer

So when I use the creality slicer, I add my own support but when I print it it turns into messy random lines that fall everywhere. When I use the generated support it works but the support is way to hard to take off. Is there different material for better support I use PLA. Is there any idea how to make my support better so my print does not go crazy.

I turn off support interface and reduce the support percentage to about 10%, this is with normal support rather than tree.

Ok Thank you I will try that.
