Turn off auto complete feature in LibreOffice Calc
Working on a massive spreadsheet ... entering a lot of AS numbers.
LibreOffice Calc often adds additional numbers when I enter a short AS number
after I have moved on to the next entry, so the alteration is easy to miss.
In this context, "AS" stands for autonomous system.

Click "Tools" in the main menu, then deselect (uncheck) "AutoInput" (or something equivalent in your local language) and see what happens.
I'm using LibreOffice 6.3.3 in Debian sid (unstable).
nadebula.1984 is using a different version of LibreOffice
My Standard Issue Trisquel has LibreOffice Version: 5.1.6.2, within which AutoInput is nowhere to be seen.
