Forerunner 255: Can't see heartrate zone in training details

Hi All. Garmin in Spanish.

When I setup a new run training, It is not possible to read the complete text in the Garmin. So, if the training session consists in 2km in HR zone 2 plus 3 km in HR zone 4, when I check the training session in my Garmin device before I start it, I only can see: "Zona de frecuencia ca" instead of "Zona de frecuencia cardiaca 2".

Can you fix it guys, please?

Thanks in advance. Kind regards.
