I have had this issue for quite a while. There are a few notes that are never suggested when I try to link to them. The notes that don’t appear seem to be single word note titles that are used in a lot of other multiple word titles. For example I have a note titled “leadership”. I also have a lot of other notes which have “leadership” in the title like “2024-06 leadership meeting”. The “leadership” note never shows up in the wikilinks autocomplete suggestions. However, It shows all the other notes that have “leadership” as part of the title.
