It is, unfortunately, the failure of the glue between the elements of the triplet. This occurs often and there are threads on cloudynights.com about it.
It is especially common with elements glued together by Balsam cement.
You can research how to unglue and then re-glue the elements, or simply chalk this up to experience and the "school of hard knocks".
