RE: Translation of two option field
Hi Nora,
In my experience when you change the Display name of an attribute, in this case this two-option field, the display name on the form is not changed sometimes. So I have to change the display name of the form field as well. It doesn't make sense, but it works in the end.
You can use the XrmToolBox plugin Easy Translator to download the current translations and see if the display name of the attribute is different from the one on the form (form field).
