Limited Options In Menus

Hello all,
I have very limited knowledge of video editing software, but have been watching tutorials. I am having a hard time following some as it seems I do not have the same options to select. For instance I am trying to do an audio sync between a .MP4 file and a .wav file. When selecting both files(in the media pool), and right click on them, I am only presented with 14 options. 28 options are what is shown on all of these tutorials. None of these options are Auto Sync Audio... and when searching for a solution, everything coming up is just to select these files, right click, select Auto Sync Audio. When I am watching tutorials I did search to see if this was a paid only option, but seems it should be within the free version. Any help would be greatly appreciated.

Seems I am unable to post the photo, so I am not sure how best to convey the issue.

Is there embedded audio on the MP4 (I assume H.264) video file?

Are you doing this on the Media Page? That's where sound syncing should take place. This is covered in depth in Chapter 21, "Syncing Audio and Video," starting on p. 430 of the Resolve 19.1 manual.
