When I press Enter key in summernote, it shows character 'n'

Question

I am using a summernote textarea field for adding a template. 

When i type something and press Enter key for next line and save it, it creates an additional character 'n' before and after that.

Example: If I type like this --> 

HELLO USER 

WELCOME

 

it shows like this -->

 

HELLO USERnWELCOMEn

 

Please help me to resolve this issue

Thanks
