That's possibly because of the continental way of using a decimal point in place of a comma, i.e. UK (and US) would write 7,760Kg but some european countries would write it as 7.760Kg (so there's a potential error of 3 orders of magnitude there). Certainly in the post it's confusing to my (UK) eyes, saying 1000Kg then 10.000Kg for 10 times as much.
Irrespective of the original dosing, the more surprising (and dangerous) thing is it didn't get picked up before it caused loss of thrust at take-off. Mistakes happen, but it does seem this one should have been caught long before it got as far as it did (the potential being there for a considerably worse outcome).
