Weekday formula not working on Excel 2016 Entreprise (PC)

Hello,

I used the following formula on a MAC  and it worked well.

=TEXT(WEEKDAY([@Date]),"dddd")

When I now open the same file on a PC (using the same EXCEL 2016 Entreprise software) it does not work.

I try entering the formula again and it shows me error (see attachment)

Note: Data contained on DATE Column is formatted as DATE.

Thanks for your help.
