User Cache TTL Not Working

I have a value in the cache right now, that should be expired. Here is the info value:

Array (    [total_cache_uptime] => 86440    [is_local_cache] =>     [total_item_count] => 118523    [total_hit_count] => 2906916    [total_miss_count] => 427072    [ucache_entries] => Array        (            [1] => Array                (                    [key_name] => Apps_Home::getLists                    [value_type] => string                    [value_size] => 881                    [ttl_seconds] => 300                    [age_seconds] => 20703                    [hitcount] => 729                )        ) )

As you can see, age_seconds is WAY over the ttl_seconds value. Why it entry still being returned??
