How can I make my list properly indented?

[DTBtrigger]

What's wrong with my marktext? I used to wrap a list, press enter, and then press backspace to delete small dots in the list while saving indentation, just like in Word. But now pressing enter will only make my indentation disappear, and I unable to use the secondary list. If I directly use tabs for indentation, anything I input will become a code block. Is there an error in my settings?

for a nested list try keeping the bullet instead of removing it with backspace

type the parent item then press enter to create the next bullet
with the cursor in that second item press tab to nest it under the first
shift+tab moves it back out

the first item needs a preceding sibling before it can be nested

you can also enter this in source mode

- parent item
  - child item

the current list indentation tests cover that exact tab and shift+tab sequence

backspace can remove the list structure rather than leave a word style paragraph indent
if tab still creates a code block while the cursor is inside the second list item please share your marktext version and a small markdown example so we can distinguish that from normal paragraph indentation
