    Highly suggest if you're going to check in the .idea folder (I would ignore it personally) try using this gitignore to configure it correctly: https://github.com/github/gitignore/blob/master/Global/JetBrains.gitignore

    I had this problem when git somehow got confused about whether files in RubyMine's .idea directory were in git or not. Doing things like git stash would clobber my RubyMine configuration. I fixed it by recloning my repo, copying .idea from the old clone to the new, and fixing my RubyMine configuration. After that it stayed fixed.

    No idea whether that's why you're having this problem, but I'd look in to whether RubyMine is having any trouble writing files to .idea, or whether anything is changing those files behind RubyMine's back.

    2. delete .idea/ folder
    3. re-open project in RubyMine
