It tells me this but im new in YAML and dont know what to do. Please Help

Code:

 Use the following website to help you find and fix configuration errors:
https://yaml-online-parser.appspot.com/

org.bukkit.configuration.InvalidConfigurationException: expected '<document start>', but found BlockMappingStart
in "<string>", line 11, column 1:
    default: default
    ^

People have said that it can be a spacing error but i dont know where. Thank you for your help
And btw in the YAML parsel it says

Code:

ERROR:

while parsing a block mapping
  in "<unicode string>", line 1, column 1:
    724c64a2-fc8b-4842-852b-6b4c2c6e ...
    ^
expected <block end>, but found '<block mapping start>'
  in "<unicode string>", line 6, column 3:
      charelsuarez:
      ^
