Some female companions say only "." to the female player char

[tos1]

At least Dacey Mormont and Brienne of Tarth sometime say "." to the female player character.

Mya Stone and other female companions say proper sentences for example:
----
str_2_woman_to_woman
Men come and go. They lie, or die, or leave you. A mountain is not a man, though, and stone is a mountain's daughter. I trust my father, and I trust my mules. I won't fall.
----

I guess the corresponding lines are:
----
str_dacey_woman_to_woman {!}.
str_npc8_woman_to_woman {!}.
str_daughter_woman_to_woman {!}. <-- I don't know the possibility.
str_event_woman_to_woman {!}.  <-- I don't know when this is used.
----

- How to reproduce it/when/why it happens:
Play as a female character, hire the female companions and wait for days till they speak the lines.

- Game version (and steam or downloaded):
AWoIaF v8.2, Warband v1.174 downloaded
(Note: v8.1 + WB v1.167 has the same problem.)
