I am not sure this is the greatest misundustanding ever.
I will try to explain one more time.
I strongly believe you have another bug (non breaking white space/unicode handling) that is affecting the way linking works.
0.7 will address that bug (Obsidian does not handle well note titles containing non-breaking space)
0.7 will not address the reference issues in here (References not updated when moving/adding files to folders), but I don;t think this is your primary problem.
As a quick test. Can you try renaming the note that is creating you issues “2020… My 30 day” to “Test”.
Now try to reference to “Test” in a new note and move it to a different folder.
