If you get the output like this then your YAML file formatting is not correct.
The indentation is very important. It is possible to use a YAML syntax checker on the net or in your editor of choice.
I personally only do a two space indentation in my files.
Your screenshot shows first 5 spaces, then 4 spaces and then 10 spaces.
Example from my test system.
fileinfo:
path:
- 'C:\Temp\*.ps1'
