How to fix MetroMessageBox Title size display problem

Question

I have strange problem of using MetroMessageBox. When typing title string of message box it cuts bottom of fonts like this:

My code is just declaration of MessageBox and it is used in simple WinForm:

MetroMessageBox.Show(this, "Some message", "Notification g j p q y", MessageBoxButtons.OK, MessageBoxIcon.Information);

In documentation (link) is maybe here problem (in file): metroframework-modern-ui/MetroFramework/MessageBox/MetroMessageBoxControl.Designer.cs:

this.titleLabel.Size = new System.Drawing.Size(159, 32);
