Relationship status translation issue

Hi there,

in relationship status settings in edit profile view, under dropdown list with relationship status, there are notes, that are only in english and I can't find in any file where can I modify and translate this.

I mean these two texts:
"Please type the name here..."
"Please specify the target name"

Could you please let me know where can I find these texts and translate it (even manually)?

I'll be very grateful for your help!
Best regards!
Adam
