Primals Disappearing - Unable to be seen, thus attacked!

After disappearing prior to the first Diamond Dust, she reappears... or at least she's supposed to. But doesn't.

Yet my party and my pet can attack them. Has happened in Garuda EX and Shiva EX, at least.

Steps:
After Shiva disappeared for Diamond Dust at around 72% HP, when she was supposed to reappear before breaking us out of the ice, she didn't, and was invisible when she was. Permafrosts were invisible, and so was she, so I couldn't attack. My party and my pet were able to though. However, my Enkindle wouldn't work for my Garuda-egi, seeing as how I didn't have a target selected. I don't know if Shadow Flare worked when I casted it on where I figured she was due to where my teammates were standing/attacking. She was able to damage me with her attacks, though, so it's not like I was invisible as well.
