Here is the illustration of map navigation tree in three levels:
1ST_LEVEL_MAP
trigger_count |           map           | group name  | groupid
---------------+-------------------------+-------------+---------
           21 | 1ST_LEVEL_MAP           | TEST/10_AAA |      43
         3994 | 1ST_LEVEL_MAP           | TEST/02_BBB |      37
            1 | 1ST_LEVEL_MAP           | TEST/03_CCC |      41
    2ND_LEVEL_MAP
    trigger_count |     map       |     group name      | groupid
   ---------------+---------------+---------------------+---------
             3843 | 2ND_LEVEL_MAP | TEST/02_BBB/GR1 |      39
               15 | 2ND_LEVEL_MAP | TEST/02_BBB/SDC     |      40
        3RD_LEVEL_MAP
        trigger_count |           map            |         group name          | groupid
       ---------------+--------------------------+-----------------------------+---------
                35879 | 3RD_LEVEL_MAP            | ANOTHER GROUP               |      47
                 3843 | 3RD_LEVEL_MAP            | TEST/02_BBB/GR1             |      39
 
Here is a sample configuration how the element type gets represented in the map:
The problem is that for such trigger count
21 + 3994 + 1 + 3843 + 15 + 35879 + 3843
The widget is not able to load.
