This is happening during last upgrades, but not always and not in every machine I own. When I upgrade phpStorm, I lost my custom keymap configuration. For example, I like cmd+r for the File Structure, and it's gone. It never happened with version 2016, but it happens most of the time with 2017.
Obviously, it's very annoying having to set everything up again and again. If I import my previous exported settings, no keymap is imported. It's weird.
I'm using mac 10.12.4.
I would really appreciate any help here.
