Baking Issues with Normal Maps

Hello, 

I am working on this tree currently and ran into some issues when I tried baking the high poly model onto the low poly one. As you can see from the pictures, some parts of the crown are not baked properly and I am not sure how to fix this as I am new to Sustance Painter. 

So as you can see from the picture,  there are some weird artifacts on 3 of the crowns and I do not know what might be causing that. 

Any help will be appreciated!
