the point "12" in TOC is created because index is automatically generated in heading 1 ( as you can see in the black circle) , and the point 13 is generated automatically by the system.
Printed document is generated with dotx template and i can't see how set the style for index items.
Thanks for support
I think you have a blank line in a topic that is set to the Heading 1 style so that creates the first line. The second one I would guess is because in the document that blank line is at the end of a page and Word is spanning it across the page break.
If you are generating your printed documentation using a Word template, you can modify any of the styles including the index in that template.
