I have created a data view webpart to display information from a multi-list datasource using SharePoint Designer 2013 in a SharePoint 2013 Online site. I added the Grouping toolbar control to the page. Whenever I change a selection of a site column in the Group By, Sort By or Filter drop down menus, the new choice immediately reverts to the previously selected site column. When I try to change it again the change sticks.
I have to make a selection in the pull down menus twice every time I want to make a change in the site column.
Any suggestions for how I can fix this glitch? Or is this a bug?
