Fit Indices Problem PreviousNext

Hi everyone, I'm running into a problem with my path analysis in Mplus working off summary data. I'm looking at two different outcome variables, and I'm testing models where I just swap out one outcome for the other while keeping the rest of the model the same. My problem is that I get perfect fit indices with out outcome but not for the other outcome (identification doesn't seem to be an issue because the # of variables is the same).

Basically, I'm looking at 6 variables (A through F) in two different models in which I keep 4 of the variables and swap out one of the last 2, keeping the models the same except for the exchanged variables. Here is the structure:

A B C all interrelated
Paths from A B C to D
Paths from A B D to E/F (E and F are different variables, models are tested with either E or F, but not both).

For outcome E, I get perfect fit indices while I don't for outcome F. Why is this happening, or, what are some things that can contribute to this happening?

We need to see both outputs.

Ugh, the output is like 20KB when the max is do I resolve this?

Found a way to put both things online:

They should not be that large. Please send them both along with your license number to
