Error when saving favourites in Pivot Table, Visualizer

HI,

I am seeing this error when saving a favourite (on catalina.out). The favourite is never saved. What can be the issue? It only happens when choosing ‘Details’ for data elements.

ERROR 2017-08-16 13:36:34,998 ERROR: duplicate key value violates unique constraint “dataelement_operand_unique_key”

Detail: Key (dataelementid, categoryoptioncomboid)=(1369, 98) already exists. (SqlExceptionHelper.java [ajp-nio-8009-exec-4])
