Comment 1 for bug 803432

Hugin is using the concept of lens and stacks. So it is not possible to separately link the geometric parameters in a stack alone (this is allowed in panotools, but not used in Hugin).
So for now Hugin prints a warning, if the stacks are incorrectly linked (changeset 624abeb108a1c8ba1bd566b74b173b4d7202c23c).
