Verify that your editor is respecting the correct .editorconfig file and what configuration is being applied.

From this thread:

This will show the settings for a file with the .txt extension, but it probably should be the filetype you are debugging.

$ vi
:let g:EditorConfig_verbose=1
:e anything.txt
Applying EditorConfig vim_core on file "/home/guyhoozdis/something.sh"
Options: {'max_line_length': '79', 'insert_final_newline': 'true', 'end_of_line': 'lf', 'charset': 'utf-8', 'indent_style': 'space', 'i
ndent_size': '2', 'trim_trailing_whitespace': 'true', 'tab_width': '2'}
"something.sh" [New]
Applying EditorConfig vim_core on file "/home/guyhoozdis/something.sh"
Options: {'max_line_length': '79', 'insert_final_newline': 'true', 'end_of_line': 'lf', 'charset': 'utf-8', 'indent_style': 'space', 'i
ndent_size': '2', 'trim_trailing_whitespace': 'true', 'tab_width': '2'}

Or you could open the actual file you want.

$ vi somethings.sh
:let g:EditorConfig_verbose=1
:e
"something.sh" [New]
Applying EditorConfig vim_core on file "/home/guyhoozdis/something.sh"
Options: {'max_line_length': '79', 'insert_final_newline': 'true', 'end_of_line': 'lf', 'charset': 'utf-8', 'indent_style': 'space', 'i
ndent_size': '2', 'trim_trailing_whitespace': 'true', 'tab_width': '2'}
