I do not know where does the "those" comes but do remember that most often there will be hints that are not applicable for the current sentence. Yes, I am surprised that "those" is even there at all, but it changes nothing. Often only a subset of the hints is applicable.
A rule of thumb: tyto, tyhle, tyhlety -> these; ty, tamty, tamhlety -> the/those
Finally, you can edit your comments, please do not split a simple comment into two separate posts, I will generally remove one of them to remove the clutter.
