I just checked with some of my colleagues in LabVIEW R&D and this is what I found:
Static VI Reference issue: This is expected behavior. A Static VI Reference will not appear in the Callees' Names or Callees' Paths property list. This is because a Static VI Reference allows you to have a VI call itself recursively, and the Callees' properties do not support recursive VI calls. I have filed a CAR (3VJDFQF2) against the LabVIEW documentation so we can indicate this fact in the help for both the Static VI Reference and the Callees' properties.
SubVI with Required Input issue: This is a bug, and I have filed a CAR (3VJDCQF2) on this issue as well.
