This is normal for AOD.
There is an acidic bac water you can buy next time or you can just palm it for a few minutes and it will liquefy again.
I've said in the past this only has to be done the first couple times then you're good-to-go for the rest of the vial because that has been my experience with the first two I've done. But here I am on my third and I had to do it again, for no reason at all, this morning.
It is what it is.
