We add Order by Data checkbox in Node tab, put it in Position group, on the right of alignment option. Select it should just use node order in data to decide node order.
1. when there is no Name column (input is 2 or 3 columns), we use link order in first 2 column to decide node order
2. when there is Name column(input is 4 columns), we use data order in 4th column, If this name column is set as categorical, then we could use categorical order.
