As you can see the system does not translate the phrase «records found».
To fix it replace the line with the following code:
<span data-bind="text: totalRecords"></span> <!-- ko i18n: 'records found' --><!-- /ko -->
The similar bug with the «selected» phrase:

Replace the line with the following code:
(<span data-bind="text: totalSelected"></span> <!-- ko i18n: 'selected' --><!-- /ko -->)
