Shift I - can't see more than one instrument/artic

After loading several flute articulations in my VST (Tascam GVI & UVI engine) I can only see one articulation when I "Shift I". It is shown as the name of my VST which I rename to Flute but the other articulations like staccato & fortepiano etc..do not appear. (I'm not using presets or Notion Instruments)
Can someone explain to me if I'm missing a step. Thanks!
