I started using the very nice Element UI components, and when I try to add the pagination component in my project using
<el-pagination @size-change="handleSizeChange" @current-change="handleCurrentChange" :current-page.sync="currentPage4" :page-sizes="[100, 200, 300, 400]" :page-size="100" layout="total, sizes, prev, pager, next, jumper" :total="400">
</el-pagination>
the text appears in chineese like this:

It also happens on their JSFiddle sample, but it's not happening on their website.
Do you know how can I use it in english?
