Could you provide a clarification?
Do you want the top 10 problems for every person in the top 10?
Do you want to filter the data to the 10 persons and then find from those in the top 10 what the 10 problems were?
It would depend how the data is set up and if the problems are unique per person or if there are problems that are repeated over several different people. Please clarify above and send data.
It's just crete the top 10 filters and drag them on filter shelf.
After it you add the top 10 by count filter to the context.
