Features differ between platforms, even for what appears to be the same app.
The App owner, in this case Amazon, build their app based on the hardware of the device delivering the app.
This is not a fault with the box or device you are using but a limitation of the App itself.
If your laptop has an HDMI cable and you need subtitles, you could hook this up to your TV.
Alternatively a Fire Stick will also give you the feature you require.
