List choices values are not displayed properly in an email

Hi, 

I've configured a workflow in order to send an email when a list item is approved. Some fields entered in the SP list need to be displayed in this email.  This is working fine, however, choice values are not properly displayed in the email. Please take a look at my screenshots. 

Filds : entreprise name (free text), date (date), amount (currency) are perfeclty displayed. Fields Request name (choice values field) is displayed as @odatatype...     

Any ideas?
