Number of store misses in management console is allways 0

Page: Caches -> select cache container -> select cache.
Configuration of the cache: replicated cache, 2 nodes in the domain, eviction size=10

In the "Cache loader" tab, there is a field "# Misses" which should show number of store misses . When I put 20 entries in the cache, first 10 will be evicted. When I try to read 10 non existing entries the cache store misses should be 10.
