Hi, i'm very new to sigil, i'm trying to understand how to add a new chapter to an already exsiting Table of contents without losing the stylesheet/code used for the Toc? I need to update the Toc because Kindle Previewer will not make this chapter a blue clickable hyperlink that takes it to the chapter. It shows greyed out in kindle previewer but in sigil it shows up as a blue clickable hyperlink

When I click generate Toc then create an html for the toc, it makes a Toc & in the chapter is seen as a blue hyperlink in kindle previewer but the stylesheet/code is not the same....

So i'm trying understand, What do I need to do so kindle previewer shows the chapter as a blue clickable hyperlink that takes you to the chapter?

I already checked the content.ocf & toc.ncx in it is showing up in both. In the content.ocf its in the manifests & the spine so im not sure what to do....
