Parse . (dot) the end of the sentence with dot notation

Where I used

What it created

I had the same issue as I use the original text as the key as you do. I just set the separator to something else than . (I used |) as I don't use hierarchical keys anyway. That fixed it for me as long as I don't use the set separator in my text.
