Read the text you're showing (backside), and even so I do realize that the specs say the product is good for "minus 54C to 250" or sth, I wonder if the bad tubes had seen freezing temps for a longer period of time - not even -54 but just -5 or -10C - before use. Not every product which can stand low temperatures when cured, can stand sub-freezing temps in storage (example ultra-rapid glue). But admitted, this is just a wild guess.
