I thought maybe that two versions of the VDL Template might have been merged together (which is not a good idea), but it doesn't look like that's the case from the image.
Can you send me another problem .sib file that shows the Glock range problem? I just realized that you're running Sib 6 and I'm not sure I was looking at things in the correct environment.
Oh, and to double check, you're using 2 instances of KP4 for VDL and Sibelius Player with Essentials?
