Band Assignment to ArcGIS Color gun

[rrjs67]

Hey

I have downloaded all the bands for the landsat 8. I did band composite from arctool box. Once you are done with composite. I have done for B5, B6, B2. I'm studying healthy Vegetation The band #s were changed to B1, B2, B3 losing the original band numbers as shown in the figure ie attached. Please suggest how to fix to False Color Composite.

I appreciate your valuable time.

Thank you in advance,
