Paint bucket tool isn't working correctly

So I was creating a face for an animation Im doing and when i tried to color in a part of the eye with the paint bucket tool it will color in the whole thing. I made sure that all my lines were connected multiple times and its still keeps coloring in the whole eye. I now have to manually use the stroke tool to create a close object so the paint bucket tool will work correctly but it takes alot of unesscessary time to do that. Anyone have any ideas that can help me out

This is the best information about the system which is really helpful for us. And I used the good information about the system. if I have an issue with that then go to the technical support. if I can activate iphone without sim which provides the good support. you can also go to the https://babasupport.org/apple/activate-iphone-without-sim/ And it is good for us. The paint bucket is working very fine.
