When I have lots of checkmarks and I want to pres enter to add another one under existing one, new checkmark is added totaly to another part of the note. Or when I press "Del" to delete empty space between todo checkmarks, checkmark bellow (and whole text) is moved not just one empty space up, but it is moved to random part of the page and often many checkmarks under it and their structure (tab placement) is messed up and or moved to different locations in the note.

This renders using and arranging lots of todo lists unposible.

This is not the first time. It usualy happnes when there is more todo checkmarks. Smallest number I encounterd this with is aprox 20 (so not even that much).

I have video and will provided it to email you send me.
