FMOD for Unity missing internal effect errors when building Unity Player for Win 64

Hi! I’m having issues when attempting to build a Unity project with the FMOD for Unity integration.

The Unity Player Build falls over with errors (seemingly) related to FMOD internal effects.

The errors are as follows:

Effect Highpass could not be found. Check that the project contains the correct native audio plugin libraries and that the importer settings are set up correctly.
Effect Compressor could not be found. Check that the project contains the correct native audio plugin libraries and that the importer settings are set up correctly.
Effect SFX Reverb could not be found. Check that the project contains the correct native audio plugin libraries and that the importer settings are set up correctly.
Effect Highpass Simple could not be found. Check that the project contains the correct native audio plugin libraries and that the importer settings are set up correctly.
Effect Lowpass could not be found. Check that the project contains the correct native audio plugin libraries and that the importer settings are set up correctly.
Effect Distortion could not be found. Check that the project contains the correct native audio plugin libraries and that the importer settings are set up correctly.
Effect ParamEQ could not be found. Check that the project contains the correct native audio plugin libraries and that the importer settings are set up correctly.

The errors are reported for both development and release Win64 builds. The version of Unity is 6000.0.16f1.6822.5931, and the FMOD for Unity integration package is 2.03.13, although I have also tried 2.03.06 and 2.03.14

Note that in our project, there are no FMOD Events that utilise these internal effects, but still they seem to cause the the build to fail when trying to build a Unity Player.

When I have added such effects to an FMOD Event, they seem to work fine in game playing within the Unity Editor.

Anyone encountered anything like this, or have any idea what the issue might be ?
