Kate replaces text instead of indenting when typing Tab on selected lines

I tried to change all the indentation settings to fix another problem yesterday, but now I have the following problem and I don't know which setting causes it. If I select lines and type Tab, I would expect the selected lines to be indented. Instead, the selection is replaced with a tabulation. For example, I start with: aa bb cc Then I select a part (what's between [ and ] is the selected part): aa b[b c]c Then I press Tab (---> represents a tabulation), I expect this: aa --->bb --->cc But I get this instead: aa b--->c How can I revert this behaviour? I'm using Kate 21.12.3.
