Date filters in the new UI do not display correctly if user language is set to Spanish.

STEPS TO REPRODUCE:
1. Login into Clarity PPM with a user whose language is set to Spanish.
2. In the new UI, add a filter of date type in the Projects or Ideas module (for instance, Fecha de Finalizacion).
Expected results: The filter box is correctly displayed, showing the two calendar icons, allowing to enter values from/to.
Actual results: The filter box is displayed, showing the two calendar icons, allowing to enter values from/to.
In English, the "TO" text is displayed separating the two calendar icons/fields.
In Spanish, however, a wrong text, "A LAS/S", is being displayed separating the two calendar icons. On top of that, the text is overlapping with the second calendar icon.
