Won't overwrite automatically

I've set the program to automatically overwrite files that already exists, but it won't listen to me. I get this dialog box everytime i upload a file:
Click here for image

My settings look like this:
Click here for image

I've tried to uninstall and install the program several times without any success.

Is this some kind of a bug?

Do you have a favorite entry for that site? Within the favorites, you can define these settings again to override the default behaviour for that site. Check if you have selected to use the global settings within the favorite's settings.

I defined the settings again and now it works perfect. Thank you for the help
