MBPro language keeps changing

I have my laptop set to Canadian English, but every now and then I see it has changed to U.S. I suspect it occurs when I wake it after it goes into energy saving mode during inactivity. Anyone else encounter this? I run Mojave on all my laptops and the same happens with all of them.

Thanks,
Thom
