reformatting .sh file doesn't do anything

Hi Folks. I finally migrated to the latest IDEA version, and I've noticed that the Reformat command does not do anything in a .sh file I have. It worked on older versions. Reformat works on a .py file, BTW. I tried both Reformat Code and Reformat File… with no luck. The attached pics show .py and .sh files before and after Reformat. Any advice would be awesome - IDEA is kind of my power-up when others at work need their files cleaned up :-)
