This is a practical question about the risk of bias summary in RevMan 5.3:

When I make a RoB summary, it only shows the '+' and '-'. Where the RoB is unclear, the box is empty, whereas it should show a '?'. Additionally, I do not know how to sort the studies in the summary table by year, now they are alphabetically ordered. 

The internet does not seem to be very helpful. 

Could somebody solve this problem? Thanks!
