Workmate WM425 vertical clamp truly vertical?

I bought the same model today and had to take it back for a replacement.
When I went to assemble it the wood work surface had a huge amount of mold
or a fungus growing from it!!!

First time I have ever seen something like that

Your first sentence is your answer,It's made by Balckened Pecker isn't it?
