Elastics index folder doesn't contain project name after upgrading from 3.9 to 3.11

Issue

After EFK stack was upgraded to 3.11, it seems I can't longer match a directory within the Elasticsearch data path with an index name. In example:

In 3.9:

[root@redhat indices]# pwd
/mnt/local-storage/infra-sc/elastic/logging-es/data/logging-es/nodes/0/indices
[root@redhat indices]# ls -lrt | tail -1
drwxr-sr-x. 3 1000080000 1000080000 20 Jan 15 08:46 project.test-rh.d2da18f1-2bb-11e9-81c0-000d3aa32fcf.2020.01.15

In 3.11:

[root@redhat indices]# pwd                           
/mnt/local-storage/lab-es/elastic/logging-es/data/logging-es/nodes/0/indices                        
[root@redhat indices]# ls -lrt | tail -5
