Hello waveheavy!
It can have different reasons why articulation changes don't work as expected. Did you go through the Troubleshooting section of the "Sibelius Integration" tutorial yet? All possible reasons that come to my mind are listed there.

If you can't find a solution there, please send the following screenshots to support@vsl.co.at.
- Sibelius "Add or Remove Instruments" menu
- Sibelius mixer
- Sibelius Playback Devices menu
- Sibelius Manual Sound Sets page of all loaded devices
- Vienna Ensemble Pro showing one of the instruments that doesn't work correctly
