I got my info from...

Number 3, says for Kieselsol, “used after gelatin or chitosan”.
Nor saying it’s right, just where I got it.
I was wondering how you got it backwards ... and now I cannot say that you did. I have a local copy of the WE instructions, and it says to add chitosan first, and I found another reference that says the same. And in the past the order was always kieselsol first. I recall reading in several places that if chitosan was added first, the wine won't clear.
FWK says to add them together.
Now I'm wondering if the order matters in any way. It's entirely possible someone decided at some point that order matters, wrote about it, and other people parroted it.
This is a good experiment for someone with two batches going -- Add K&C to one and C&K to the other to see if it matters.
@Eric336, this is situation normal, veering off topic into (hopefully) related discussions. Or not related.
What is your wine and why do you think it needs another round of fining? I should have asked that question immediately after warning you to not use K&C again.
If it's fruit wine, a pectin haze is a possibility, and either way a protein haze is possible. For pectin, add pectic enzyme -- it will not hurt your wine if you add it unnecessarily. For protein you can fine with bentonite. Also, Bob pointed out that isinglass can be used for polishing.
