Double deletes in editor

First time posting here, so if I'm doing something wrong, let me know!

Anyway, I downloaded EAP 2017.1 last week and encountered an annoying little bug. Every time I enter the 'delete' button it gets triggered twice.

Only happens in this version, even after a reinstall. EAP 2016.3 and all other software handle this as it should. 

I'm using a MacBook Pro with macOS Sierra (10.12.2) and an external Apple keyboard.
