Logi Option+ swap two keys on Mx Keys on MacOS CSA mapping

I have a French-Canadian Logitech Mx Keys for Business (model 920-011645). I use it with both MacOS and Windows with Option+.

When I use it on MacOS (Canadian CSA) the Key for \ and Ù are swapped when using apps. Although when I use Keyboard Visualizer the key shown is OK.

The problem does not appear on Windows.

The problem is very annoying.

Do someone know how to correct this problem?
