Has anyone ever had this?

the -1.#IND00e+000:-1.#IND00e+000:-1.#IND00e+000 change to -1.000000e+000:-1.000000e+000:-1.000000e+000 when changing the selection from header and back again.

does anyone know if any issues that could result from it? also the dae is attached.

Yes, I get that when the detail 0 mesh is weird.

Like uh, two unconnected spheres, or a bunch of unconnected blocks.
Or just a series rings in space...

usually happens when detail 0 isn't "continuous".

I guess the autocalculator uses some assumptions that totally break when your detail0 is wonky like that.

I'd wager something similar is going on with your model, on perhaps a less-obvious scale.

in that case i know what the problem is

That mesh looks like it needs a good X-Form Reset and Edgesplit/Smoothgroups on top of that.
It has got some wonky lighting and its uniformly smoothed (YUCK!)

Just copypaste MOI from some other, similar sized model.
Of course, if you're good with physics and maths and know exactly how do you want your ship to behave, you can try to calculate that yourself, as it's not that difficult (FSO uses, as far as I know, a normal MOI tensor).
