strange behaviour of lists and indentation in document notes

i obseved a strange behaviour of scrivener regarding the formatting of text organized in several paragraphs within a document note. you format the text, it looks fine, but sometimes (not always) when you revisit the text, the formatting has changed. i couldn’t find a pattern yet, but it does thinks like: turn the first item of a bulleted list into a paragraph with indentation, add indentation to paragraphs which had none, change the amount of indentation for list-items or paragraphs in an upredictable manner. furthermore, it is hard to change the formatting once it’s been jumbled up. before going into further detail or trying to find out exactly what happens when, i wanted to ask whether this bug is known already.
