$string['datatables_info'] = 'Showing START to END of TOTAL entries';

This string works correctly (Showing 1 to 10 of 99 entries) but some translations change the key strings 'START', 'END' and probably 'TOTAL' causing JS to not be able to find them to replace them.

For example, in Spanish language (moodledata/lang/es/block_configurable_reports.php) the string has been translated as

$string['datatables_info'] = 'Mostrando INICIO a FIN de TOTAL entradas';

and the keys are displayed literally: 'Mostrando INICIO a FIN de 99 entradas'.

The translations must be

$string['datatables_info'] = 'Mostrando START a END de TOTAL entradas';

Always keeping START, END and TOTAL without any modifications
