why each time I do a file sync, it showed me that a file trasnfers is occured

[Adrian Mak]

I executed
rsync --progress --verbose --stats  --recursive
test at 100.100.100.100::test /home/test2 --stats

but each time it showed me files are being transfer but actually the
files is not changed or updated any.
for example,

          12 100%    0.00kB/s    0:00:00
abcdef
          44 100%    0.00kB/s    0:00:00
demo2
           0 100%    0.00kB/s  157:26:58
demo3
           0 100%    0.00kB/s  157:26:58
xyz
           0 100%    0.00kB/s  157:26:58
