ILM policy is set: rollover daily / delete after 31days.  
Index is deleted after 7days (ignoring 31days setup)  
I tried to change the value 30,31 and no change.  
This ILM is used by 2 templates and 2 indexes. test\_xxx, and production\_xxx  
ILM works on test but does not work on production.  
Is this a BUG?  
How can I troufix it?

Policy conf:

> {  
> "sys\_metrics\_mediator\_policy" : {  
> "version" : 2,  
> "modified\_date" : "2020-03-13T16:00:58.131Z",  
> "policy" : {  
> "phases" : {  
> "hot" : {  
> "min\_age" : "0ms",  
> "actions" : {  
> "rollover" : {  
> "max\_size" : "20gb",  
> "max\_age" : "1d"  
> }  
> }  
> },  
> "delete" : {  
> "min\_age" : "31d",  
> "actions" : {  
> "delete" : { }  
> }  
> }  
> }  
> }  
> }  
> }

from the list see 31 test indices available and only 7 from production

was set to 7days and changed to 30Days later.  
New indexes created are probably not accepting the changed value.  
Do I have to refresh something or is this a BUG?  
I have a version 7.4.2
