Robocopy does not overwrite when copying a single file, even with /IS

I can't make robocopy to overwrite a single file, even with the /IS flag on:

C:\>robocopy.exe "\\srv1\D\SRCFOLDER"  "\\srv2\D\DSTFOLDER" "test.txt" /IS

I always got:

               Total    Copied   Skipped  Mismatch    FAILED    Extras
    Dirs :         1         0         1         0         0         0
   Files :         1         0         1         0         0         0

Is anyone able to overwrite a single file? Or is it some kind of robocopy 'bug' ?

Note: I use robocopy to copy a single file because I need the bandwidth control option /IPG:xxx Thanks.

UPDATE: thanks to Lenniey comment I added some info, here the complete output:

Even if the status is modified the file is skipped!
I got crazy to reproduce this 'bug', the only way I found was to rename the destination file \\srv2\D\DSTFOLDER\test.txt to something else, then rename it back to test.txt. After the rename the file is skipped forever.

Try /is and /it in combination. Also use /v (and maybe /ts /fp) to display additional information. – Lenniey – 2017-01-18T10:15:16.260

Thanks @Lenniey, to reproduce this 'bug' you need to rename the destination file, and then rename it back to its original name, in this way you make robocopy skip the file! – StefanoV – 2017-01-18T11:29:20.143

So...did you solve it? Can't really follow you there – Lenniey – 2017-01-18T12:42:31.257

Is not solved, but I can workaround avoiding renaming destination files. – StefanoV – 2017-01-18T13:22:24.590

Could you elaborate what you are trying to do exactly? – Lenniey – 2017-01-18T16:46:24.003

In outer synthesis: try to execute two times this command: robocopy.exe "\\srv1\D\SRCFOLDER" "\\srv2\D\DSTFOLDER" "test.txt" /R:0 /IS /IT /NODCOPY /IPG:10. The second time the file is not copied. – StefanoV – 2017-01-20T13:25:00.643
