**Versions** (relevant - OpenSearch/Dashboard/Server OS/Browser):  
2.18.0(was 2.11.0)

**Describe the issue** :  
I have a cluster 2.18.0 (was 2.11.0). And created simple ILM policy. And policy work only with action rollover by age. And didn’t work with min\_size or min\_primary\_shard\_size. I got “Pending rollover of index”. And min\_index\_age is updating every 5m. But other conditions didn’t.  
Manual rollover is work. I recreated policy. Update cluster from 2.11.0 to 2.18.0
