No cards after Previous trick in results panel

[BillAust]

I am looking at the results panel card table in either of my Windows 10 pc on http://www.bridgebase.com/client/client.php Moving through tricks using the right arrow works fine. But when I click on the left arrow to get the previous trick, the number of tricks changes and an extra card appears in each hand, but no cards shown played. This problem is not present on my iPhone 6SE and on my iPad 4.
