Puppet file_line doesn't work with agent rather with apply - regex

Question

I am trying to add a line and replace others with puppet file_line resource. I have a very strange behavior. Here is the code:
file_line { 'bashrc':
ensure => present,
path => '/user/.bashrc',
line => 'HISTCONTROL=ignoredups:ignorespace:erasedups',
match => '^HISTCONTROL\=',
}
file_line { 'sysctl_conf':
ensure => present,
path => '/etc/sysctl.conf',
line => 'net.ipv6.conf.all.disable_ipv6=1',
notify => Exec['/sbin/sysctl -p'],
}
I have this line: HISTCONTROL=ignoredups in the .bashrc file. When I run puppet agent -t it just appends this line HISTCONTROL=ignoredups:ignorespace:erasedups to the file and the original line HISTCONTROL=ignoredups is still there. More interesting is that the second file_line resource istn't executed at all.
But when I run puppet apply -e "include module", the line in .bashrc is replaced and the net.ipv6.conf.all.disable_ipv6=1 is appended to /etc/sysctl.conf.

Can someone explain this please, or how to fix this?
Thanks
