Mixing English operator labels with Vietnamese ones.

[cacious7]

I have this implementation of the query builder with the following props
<QueryBuilder v-model="queryModel" :filters="queryFilters" :max-depth="3" language="en" >
The problem is that even if we have language as en (English) but I am still getting some operators, like for strings in vietnamese.

But some are still showing in English, so there is a mix, despite the language prop being set.

I have also noticed that the language prop is documented but not implemented.

Why is this the default behavior please help me fix this.
