To fix this, please make a support ticket here:

Tell them that this happened and make sure to include this screenshot. it might take like, 3 days, but they'll make sure you get the credit.
Hopefully, they'll be releasing a new and fixed version of trials when they release Olympus season 4, but we'll see. This is a known issue though, so they should be working on it.
For future trial attempts, if you're finishing Zulrah while in the fire or ice phase, make sure the fire/ice pool isn't active or this will happen.
Good luck!
