Lines that shouldn't be translated

[Dr. Jones]

In crowdin there are some lines that are coloured in grey and that are accompanied by this warning: "the string is hidden and should not be translated". This two, for example:

evt-shamanHut-heal-infected
The shaman shook his head when he looked at $name's wound. We would need to pay extra for ingredients capable of healing such an infection.

evt-shamanHut-heal-infected-2
The shaman began a ritual in which he treated the wounds of $name. [A couple of beheaded mice later|After digesting what seemed to be a stew comprised of all kinds of bird parts] $name felt splendid.

So, is this an error from crowdin or do you really mean that this shouldn't be translated?
