I thought of this but I figured that Tetenal will never admit to a filling mistake. I wouldn't if I were them. (Perhaps I'm being a bit too negative here.)

Oh, they did in my case---eventually! I even got a replacement package of RA-4 2,5 liter kit. Needless to say, the replacement package was also defective, just like the product is.

First, they said no one has never had any problems, but in the end, they said they will reconsider the formulation to fix the problem. I got a feeling that they knew the problem or at least was suspecting it to begin with. Maybe they were lucky to have mostly non-complaining customers.
