Due dates duplicating for boundwith records after using the browser "back" button

[saseestone]

We got a report via SearchWorks feedback (from a library staff member) that praised when we show the due date from the parent record on the child record in "At the library". But the feedback was qualified that the due date "displays twice". It appears that the due date is duplicated each time the browser back button is used. This seems to happen on both the parent on the child record. But it's particular obvious when you click on a child record, then the link to the parent record. The only way to get back to the child record is to use the browser back button.

Here's a screen shot after using the back button twice on a child record:
