you altered the table and added a new column [date1]
the table [Metrics].[dbo].[x64_Restore_Metrics_All_Temp] now has four columns, but your insert has only three.
if you do insert into table without a column list, your query has to match teh number of columns(that are not identity and not calculated)
just change to have the right columns you want to inser:
Insert Into [Metrics].[dbo].[x64_Restore_Metrics_All_Temp] ([date],[bytes],[Whos])
