Help with sieve

Dear Experts, I am having following script which is working perfectly on 3 server but not working as expected on new server.

require ["fileinto","imap4flags","envelope","body"];

#1 if allof (header :contains ["Subject"] ["test"] ){ setflag "\\Seen"; addflag "\\Flagged"; addflag "BUG"; }
