Does anyone know why this is?

Hi and welcome,

Bounce Selection is used with the Audio track > Audio Events. You have Instrument Track selected. Do you want to do Render In Place?

It’s not available when using an audio track either. Yes I do.

It is not for tracks, but for events. These very basic things are also explained in the manual
