Hi! I'm having the following problem when trying to restore an index snapshot: `[illegal_state_exception] alias [x] has more than one write index [y,z]`. I followed the following [resolution](https://www.elastic.co/pt/blog/troubleshooting-elasticsearch-ilm-common-issues-and-fixes) but I came across another problem: the 'y' index appears with the 'is\_write\_index' parameter set to true, the 'z' index does not appear at all. Using this methods 'GET \_cat/aliases/z' 'GET x/\_alias'.

Elasticsearch version: 7.9.3
