TM duplicates + older TM duplicates being auto-inserted in Studio 2019 Editor???

I have two problems/questions:

(1) my TM seems to have duplicates, even though I could have sworn I set it up not to retain duplicates. Is there any foolproof way to ensure that my TM does not end up with duplicates? That is: if there are two versions of a translation unit, I always what the older one to be deleted.

(2) each time I move to a new segment, and there is one of these duplicates in my TM for the next segment, Studio 2019 inserts the older one automatically, rather than the newer one, which is obviously preferable. What am I missing here?
