Hello. We have a multi tabed worksheet loaded in BOX. Each tab had a freeze panes engaged, and a filter option at the top of each column selection. 

We have successfully used this file for 9 months.

Today when we are engaging with the file via the Excel Online feature of Box, some of the tabs are having issues with their filters. We can't engage the filter if we have a freeze panes on. If we take the freeze panes off, then we can use the filters. Please note, that this worked last week. Its like a sudden update of either Excel, Box or soemthing in our browser that is now making BOX impossible to use without the benefit of both the filter and freeze panes. Anyone else having these issues? 

Please help.
