Hi all.   See attached picture.   Some how, on a drawing with multiple sheets of similar parts, the last two sheets had a strange thing happen with one dimension.   The dimension arrow lost it's "tail" (circle).    Also, the space between the two inward pointing arrows now has a connector line (arrow), whereas other similar dimensions on other sheets do not.   How did this happen, and how can I fix it so that the dimension arrow gets its "tail" back, and the connector line between the dimension arrows disappears?   Thanks.
