Look at the reindexing notes in the $CCP4 program documentation -
general section.
in P6i there is a random possiblity of indexing as hkl or kh,-l - both
equally correct..

yes. I use HKL2000 to process the data. I will definitely try to
reindex my data. But why the data sets at inflection wavelength and
remote wavelength did not have this kind of problem ?

Did you try reindexing?
