Add Main Menu item

I’ve recently updated from Kodi v16 to Kodi v17.1 and the confluence skin on a Amazon Firestick. In the skin settings the Movies and TV Shows items are greyed out, they were present in the previous version,. I want to add them back in, how do I do that? Everything I’ve tried to date has failed either due to the instructions being just plain wrong, obsolete or various options non-existent in the version I’m using. I have no clue about Kodi, skins, the terminology used in the posts I’ve seen, the underlying file system or anything remotely connected to this app on a Firestick, I’m VERY new to this so explicit instructions are not just helpful, but necessary for me. I’m extremely frustrated with this. Any assistance would be greatly appreciated. Thanks in advance.
