Here’s what happened: One day, I started logseq as usual and found the contents page was empty: SOB:. I don’t know what happened, and then I found that the “note class” page contained the contents of the original contents page, so I tried to copy the block from the “note class” into the contents page, so after the operation was completed, I found that there was a small pencil symbol behind each page, I don’t know why, if someone can answer my doubts I would be very grateful.
Welcome. This old post seems mentioning the pencil icon. Could be possible to fix it by editing the block in an external editor.
