Symptoms
With English selected in the website language switcher, some page content still appears in French across one or more Canadian locations.
Cause
Dual language (EN | FR) had been enabled and French content was populated in Gorilla Dash (GD), resulting in mixed English/French on the English view. In the resolved case, French content had been copied from the French site.
Resolution
Restore the English content by copying the English version from the US site into the English language side in GD. This returned the Canadian sites to full English when English is selected.
