MS Access and problems with Pivot Tables

Question

We have a number of users who are on different versions of office. A few years ago we discovered an issue with Pivot Tables, namely, if an XP user on service pack 2 had changed any of the selection criteria on the pivot table subsequent users could not change these back. I was told to install SP3 on these PC's and that resolved the issue, i then recreated the pivots. However, a number of our pc's have changed hands within the office and someone with SP2 has changed the view and we can not change it back?

Does anyone know how to resolve this ?
