Space in UCD component names not supported by buztool.sh (UCD toolkit for Z) from UCD v6.2.7

It appears that the buztool.sh script from UCD v6.2.7 does not handle ucd component names with space even the name is enclosed with double quotes (").  Space in the UCD component name is considered unknown parameter.  My understanding is that ucd component names with space are supported in the previous version.  Why are spaces in name not supposed in this version?   The following is BUZTOOL step executed in BUZRJCL:

//BUZTOOL  EXEC PGM=BPXBATCH,REGION=0M
//STDOUT   DD SYSOUT=
//STDERR   DD SYSOUT=
//STDPARM  DD
SH /opt/ibm-ucd/agent/bin/buztool.sh createzosversion
