I have created a data set and have category option combos attached to the data elements
Data (January 2021, December 2020, November 2020) has been entered in a dataset on android tablets and synchronized with the server.
Although I can view the data synched with the server on the Data Entry Application, data elements are not showing values in the pivot table. I replicated it on demo.
I ran analytics and cleared cache several times, there is no change.
