MacOs Catalina 10.15.3
CC2019 version 23.1.1
AI2020 version 24.2.1

Only seems to occur when the text is aligned to the centre, set as point type and has tracking applied to it.

We have artwork files created in CC2019. When opening one of these files in AI 2020, version 24.2.1 on either Mojave or Catalina, text that is set up with tracking, is point type (instead of area type) and centre aligned shows a significant movement to the right.
As you can see from the attached .gif of the two files, there is one instance where there is no tracking applied on text, which is on the word "Helvetica" and this doesn't move at all between versions. This text is also left aligned.

We work in an accuracy critical business where later versions of artwork are now being opened in AI2020 after we've upgraded from CC2019. To have text moving around from one version to another is potentially very dangerous for us if these movements aren't picked up by operators.

2019 & 2020 AI pdf files attached. The 2020 file is just the 2019 file opened and saved in AI2020 which shows the font movement.
