TestLink

I'm new to TestLink, so this question might result stupid.

In version 1.9.8 the panel for generation of the Requirements Specifications Report showed a set of over 16 option-boxes (translate to something like "Show table of contents", "Numbering header", "Scope", "Author", etc) that are misssing in our machine-migrated and upgraded (1.9.16) installation.

I've unsuccessfully searched
* previous and current config.inc.php and custom_config.inc.php files for missing configurations.
* forum.testlink.org for any discussions on this feature being discontinued or simplified.
* mantis.testlink.org for bugs in several categories ("Reports", etc) for related bugs or requests.

Is it an intended change in Testlink or is it likely only a bug in our installation?
If it's an installation bug, could anyone please provide some hints on what could possibly be wrong?

Thanks in advanced

Some friends are users of v1.9.13 and v1.9.14 and report the checkboxes are also missing in their installations. It still could be a configuration issue but in case of functional reduction/simplification/refactoring it would have happened before v.19.13.
