display unwanted information

hello
When I want to create a document or read at the end of the document are displayed these lines:

bp_docs_last_editor:
1
bp_docs_settings:
a:5:{s:4:"read";s:13:"group-members";s:4:"edit";s:13:"group-members";s:13:"read_comments";s:13:"group-members";s:13:"post_comments";s:13:"group-members";s:12:"view_history";s:13:"group-members";}
bp_docs_revision_count:
3

How can it no longer displayed
