In templates, does the Value have the Fillup option by default?

[xp15417788]

i want to use the template below to parse a multiline commands, but i find Value like "protocol" and "vpn_instance" be filledup by default, how can i avoid it and retrieve the correct empty value? It feels strange, but i have no idea, I would appreciate some advice.

template is below,

Value Filldown acl_name ((\S+|\d+))
Value Filldown description (\S+(\s+\S+)*)
Value Required rule_num (\d+)
Value Required action (permit|deny)
Value protocol (ip|tcp|udp)
Value vpn_instance (\S+)
Value source_ip ((\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3})|any)
Value source_wildcard ((\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3})|0)
Value source_port ((eq|ge|le) (\S+|\d+))
Value dest_ip ((\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3})|any)
Value dest_wildcard ((\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3})|0)
Value dest_port ((eq|ge|le) (\S+|\d+))
Value dscp (\d+)
Value counting (counting)
Value List NotParsed (.*)

Start
  ^acl number ${acl_name}
  ^\s+description ${description}
  ^\s+rule ${rule_num} ${action}( ${protocol})*( vpn-instance ${vpn_instance})*( source ${source_ip}( ${source_wildcard})*)*( destination-port ${dest_port})*( ${counting})* -> Record
  ^\s+${NotParsed}
  ^# -> Record

raw command output is here,

acl number 2000
 description for-nms-vty
 rule 5 permit source 172.16.0.0 0.15.255.255
 rule 10 permit source 192.168.0.0 0.0.255.255
 rule 20 permit vpn-instance IBMGT source 172.16.0.0 0.15.255.255
 rule 35 permit source 1.1.1.0 0.0.0.127
 rule 45 permit vpn-instance IBMGT source 192.168.0.0 0.0.255.255
 rule 1000 deny
#
acl number 3333
 description dhcp request
 rule 5 permit udp destination 10.81.40.4 0 destination-port eq bootpc counting
 rule 10 permit udp destination-port eq bootpc counting
#
acl number 3334
 description dhcp reply
 rule 5 permit udp source 10.81.40.4 0 destination-port eq bootps counting
#

the result returned ,
