Loading an old Indesign file (version 2016 or older) in the new Version Indesign CC2020 causes a new bug.
1.) I use Indesign CC 15.0.1 (2020)
2) Open an old file of Indesign with many defined paragraph styles (from 2016 or older) --> try to edit some texts use text cursor klick in a textbox and type a 1, a 3 or a 4 on the numpad.
3) I expect that the numbers 1, 3 or 4 to be typed.
4) The paragraph style changes to another style without any shortcut set in the file or the paragraph style.
5) File type .indd and .zip are not allowed, so please load the file via this link: https://filehorst.de/d/dbfJbHwy
