On the first two charts you can get a detailed dialog through the context menu. The detailed dialog also contains details on the CCRs.
When it is necessary, each correctness checking report (CCR) is cached like other events (Function, Messages, Collective Operations, etc). All CCRs are put into each level of the cache. The CCRs are not crowded so each cache level contains the same information. It may lead to extra memory usage but this is unlikely since the total number of CCRs is not expected to be large.
