"EXEC sp_configure 'fill factor', 100" Does not take affect

The current fillfactor of the server is set to 95, I have been trying to change it back to default 100 but the sp_configure commands is not taken into affect. Below is the script I run and the result of it.

Any ideas why the fill factor won't change from the current value 95?

SELECT @@version AS version
go
EXEC sp_configure 'show advanced options', 1;
GO
RECONFIGURE;
GO
sp_configure 'fill factor', 100;
GO
sp_configure 'fill factor (%)', 100;
GO
RECONFIGURE;
GO
EXEC sp_configure 'fill factor (%)'
