Code appears on Homepage

Hello, using this plugin, I have inserted two codes into the header. When doing so, I left a 1 line gap between them.

However, when I saved and returned to my site, the code appears on the top of my homepage! How do you add 2 codes into the header without this happening? In case you’re wondering, 1 code is for google analytics and the 2nd one is for google adsense.

Thank you!
