The date plugins are buggy. I don’t recommend using them.
You can get the Weekday name from a date without using any plugins as follows:
- Create a lookup column that lists the days of the week, beginning from Sunday. This column can be anywhere, but I usually have it in a dedicated “Lookup” table
- Use a Math column to get the Weekday index number of the date in question:
Weekday(Date)-1 - Use a Single Value column to take the above index “from start” of your weekday lookup column.
