What's wrong with my nine patch image?

I'm trying to make a patch 9 file for button so it looks like a drop down. The file worked fine before I tried to add the little drop down icon to the image and have it not stretch that part. This is what it looks like in the e开发者_高级运维ditor:

Here is the actual file

The line on the right should probably be one continuous line in the center so that text is placed in the middle of the dropdown.
