Yes there is something weird.

Did you also get this message?

“Python compatibility enabled. List index will start at 0, run index:=1 or of:=1 to disable Python compatibility.”

[[11,12],[21,22]][1,1] in command line gives [[11,12],[21,22]]([1,2]) in history.

When index:=1, the previous line in history is displayed as [[...]][2,2] in command line.
And then:

[[11,12],[21,22]][1,1] in command line gives [[11,12],[21,22]]([0,1]) in history.

Ok I did not explain anything and just gave more details, but I don’t find some logic explanations. I am disappointed by this behavior, because:
- Indexes should both be decreased / increased.
- Displays either in history or command line should be the same. (UX rule)
- User inputs should not be changed. (UX rule also)

Off topic: I also notice that history recall of affectation lines also changes command line in CAS, eg: index:=1 becomes 'index':=1 and then "index":=0 and leading to an error.
