Help with Grid Util from directory

Hi Guys, I need some help with the grid util feature, i found it on the directory, is very useful and have a lots of great features.
The problem is that some aspects can not be edited, at least I don’t know how to do it, so if there is a way to solve my issue please help.

I have a filter in a column on the grid with Double type data, so if I insert a number with a dot, the filter works perfectly, but if I insert a comma instead of a dot, is showing a message error that I would like to edit just for language purposes.

This is the code from the grid util feature that I would like to edit:

 public <T extends Number & Comparable<? super T>> RangeCellFilterComponentTyped<T, TextField, HorizontalLayout> setNumberFilter(String columnId, Class type) {
        return setNumberFilter(columnId, type, String.format("couldn't convert to %s", type.getSimpleName()), null, null);
    }

Thanks in advance guys, Cheers
