I have a problem with the module customContent. Any help will be appreciate because I don't know what to do

So I run CMSMS with the latest version of customContent and FrontEndUsers. The cachable flag of all my pages is not set and a user is logged (module FrontEndUser). In my template I have the following code
...
{cms_module module=CustomContent}
#{$customcontent_loggedin}#
{content}
#{$customcontent_loggedin}#
...
The rendered page look like
## hello #9#
The first call to {$customcontent_loggedin} give an empty string. The second give the correct userid. It seams that calling {content} has a side effect and initialize {$customcontent_loggedin}. As the CustomContent's documentation explain calling {cms_module module=CustomContent} before {$customcontent_loggedin} should do the trick.
Why is the customcontent_loggedin only set after I call {content} , that's my question. Do you have any idea about this problem ?
Thanks in advance for any help you can give me
