When I work in track changes and confirm one date with ctrl enter (autopropagation enabled), it copies this particular date to all other segments as target. To illustrate:
Segment 1: 01.03.2020
Segment 2: 02.11.2020
Segment 3: 11.08.2020
Now when I use ctrl insert in segment 1 and then press ctrl Enter, all 3 segments become ... 01.03.2020.
So we have
Segment 1: 01.03.2020
Segment 2: 01.03.2020
Segment 3: 01.03.2020
Which is nonsense and which casued me a complaint from a client because I overlooked it.
I had this problem in Trados 2017 and as I see, 3 upgrades later it still exists in 2021.
