I'm so sorry you are having difficulty with the way Bluestacks displays iReal pro on your computer.
As you have been told, we have no control over the functionality of the various emulators.

I'm confident that on your native android devices iReal pro functions and displays exactly as designed.

Please send a screenshot from your android device to support@irealpro.com if the app is not displaying correctly.

I have never tried the French translation version so I can’t tell if there's an issue there. That said, you are the first to report this anomaly.
