Show comment is appearing over 1000 rows away

I created a copy of a calc worksheet that contained comments. When i hover at a cell with a comment it appears next to the cell. If I select ‘show comment’ for editing the comment it will appear over 1000 rows down the sheet, difficult to even drag it back into place. Is there an easy way to fix this?
