Wow! This model needs a lot of work.
First, the parts aren't align with the bones which will result to a lot of animations problem (displacement in a certain position of an animation)
Second, the model is (with a little work) perfectly compatible with Cloud's animations. Why did the person that created it used modified animations ? Cloud use a lot more than these two animations in the game, so in some case you could get some serious problems with this animations. My advice would be to port this model onto the Cloud's animation.
Third, well, this white problem seems weird. Seems like your files got corrupt somewhere. Beside, Ifalna doesn't show anything with this model which mean that there is something wrong with it. I'll look into it when I have some more time.
