Hmmm, 1 more try, then I give up ;-) Normally a readscript injection injects the ERC slave control, which affects the FBMs, into Figure 1, simply because Daz coded the deltas to (always) apply to "Figure 1". (Note that this means the very 1st figure loaded into a new, virgin scene, not Figure 1 on the UI, which is/can be different.) FII is based on removing all references to Figure 1 from teh injection files. In this case the ERC slave control is directed to the currently selected figure, regardless and irrespective of which model it is. This is, normally, what you want/expect: both the actual morph deltas and the ERC slave control injected into the same figure. So using FII it is possible to inject V3 morphs into M3, but selecting M3, and then loading a V3 morph - but why would you, with or without FII? Poser will not inject it incorrectly because you are using FII. On the contrary, Poser will load it incorrectly if you are NOT using FII, and have more than one Mil3 figure in the scene - which is what fixer is complaining of.
