Pycharm: Auto indentation not working on specific file

PyCharm Version: 2017.2.3

Build: PY-172.3968.37

I have a python file where the auto-indentation is not working properly.  All of my other files are formatted properly according to PEP-8.  The indentation on some files is done properly.  I created some new files, which also get improperly formatted.

The settings for the project Editor>Code Style>Python are set as follows:

<Tab> is only indenting the lines 2 spaces.  If I manually correct the indentation according to PEP-8 and then hit Ctl-Alt-L, the indentation in the file is set back to 2 spaces

During my investigation I found a couple of .editconfig files and deleted them, but that had no effect.  I also tried disabling the EditorConfig plugin, but that also had no effect
