Can’t remove comma seperator in (free) shipping causing issues

Woocommerce doesn't let me remove the comma in the Free Shipping option, resulting clients to get free shipping when they shouldn't. This seems to be a solution for the Free Shipping issue, but I can't apply the solution. It wil always say 250,00 for instance.

Anyone who has this same problem?
