No problem, happy to hear you managed to resolve those errors.
This warning is benign. FMOD Studio has a Localized Audio Tables feature, which will produce a separate bank for each language being used - the example project has three localized banks. By default, the FMOD for Unity integration loads all bank (which you can see in the Initialization section of FMOD Settings in Unity), so these two warnings are being produced by the integration trying to load two of the localized banks after already loading the first.
For the purpose of following along with the Karting minigame tutorial, you don’t need to resolve this warning. However, if you do want to resolve it anyway, you can change the “Load Banks” option under the Initialization section of the FMOD Unity settings to “Specified”, and then manually specify the banks to load, excluding additional versions of the Dialogue bank.
