Labels and lang oerriding

Hello...
i am substituting field and tab labels so that they have the correct value according to who views the profile.
It works fine at the frontend but in the backend the whole language string shows as label.
 

Is there a substitution if statement for the backend like [cb:if reason="backend"] or is there any other workaround to deal with this issue?

Than you.

Backend doesn't run substitutions so you'll see the full string.
