Hi Bobby, sorry for the delay, had a schedule change yesterday.
The file you sent me does not have any of the Template defined instruments in it. As in, the "- VDL Template 7.0a" ensemble is not there at all - I'm surprised things are working as well as they are. You'll need to select instruments from this ensemble to make use of the Template. (I've attached an image of what your Add Instruments dialog should look like.)
Ultimately, the issue with the Drumset you have in the score is that it has sound IDs that do not match what is in the VDL Template sound set. Of course, in the meantime, Sibelius is trying its best to "fallback" to what it thinks is the closest - you're seeing/hearing the result. Anyway ...
Please review the Readme PDF for working with the .sib template file - page 9 in particular. A Sibelius Manuscript Paper can also be generated by following the instructions in Appendix C: Export Manuscript Paper, page 24.
Also, please attach a screen shot of your Playback Configuration.
Once you get this sorted out, let me know how it goes from there.
Hugh
