No git 'Commit' button for git after moving from Windows to Linux Mint

Hi,

I recently moved from Windows to Linux Mint and installed PhpStorm and then imported the settings etc.

Everything appears to be working perfectly except when I go to commit changes. The button to press is simply not there, only the cancel button is available to click. (Shown in the below screenshot)

I tried creating a new directory and then doing git init but that doesn't work either.

I am still able to commit and push changes to remote branches perfectly when using the terminal so I have no idea why the button is simply not being displayed.

I have tried changing the version control settings and restarting many times but nothing works.

Any help at all would be greatly appreciated as I miss being able to commit and push changes from within PhpStorm.

Thank you
