Putting it out here, I have two input source and the number values were set as int64 and integer values for both datasets may contain integers up to 10 digits. Having said that, one of the output in the select tool displayed the number subsequently in millions automatically while the other one did not.
I was unable to locate anything which I can toggle to prevent the select tool in displaying the data in millions. Hopefully I might chance upon some advise regarding this here, thanks!
