Installing Dragon professional 15.3 and Studio 2021 / comma instead of the apostrophe

I installed Dragon profesionnal 15.3 and Studio 2021 on Windows 10 pro for some days ago and now when I am dictating, I have everywhere a comma instead of an apostrophe. Can somebody help ? I have a typematrix keybord with bépo. In other type of files like Word, I haven’t this problem.
