886718 - allow better translation of one string

Original string has different translation depending on object_type.
I created several new strings with hardcoded object_type and
only left as variable in string "label".

This is quite ugly code, but I prefer it over ugly sentence as suggested
in:

(even if it is grammatical correct).
