Multiple calls of usebundle with data containers result in some unresolved variables

In the following bundle (also attached):

<pre>
bundle agent test
{
vars:
"json1" data => parsejson('

{ "zero": "0", "more": ["hello","test"] }

');

"packageinfo" data => parsejson('

{ "name": "php", "old_version": "5.3.3-27.el6_5", "new_version": "5.3.3-26.el6", "reinstall_list": ["php", "php-common", "php-cli"] }

');

methods:
one::
"print_json" usebundle => show(@(json1));

two::
"again" usebundle => show(@(packageinfo));
}

bundle agent show(data)
{
reports:
one::
"zero: $(data[zero])";
"more: $(data[more])";

two::
"package: $(data[reinstall_list])";
}
</pre>

Using multiple usebundle calls, gives me a list of unexpanded variables. Please see the following sequence of outputs:

[root@hub ]# cf-agent ./test_container.cf -b test -K -Done
R: zero: 0 <<== this is expected
R: more: hello
R: more: test

[root@hub ]# cf-agent ./test_container.cf -b test -K -Dtwo
R: package: php <<== this is also expected
R: package: php-common
R: package: php-cli

[root@hub ]# cf-agent ./test_container.cf -b test -K -Dtwo,one
R: zero: 0
R: more: hello
R: more: test
*R: package: $(data[reinstall_list]) <<== where does this come from?
R: zero: $(data[zero])
R: more: $(data[more])*
R: package: php
R: package: php-common
R: package: php-cli
