Hello,

We have time series indexes created daily in Elasticsearch. We upgraded from version 7.10.2 to 8.10.2. While running our tests, we observed that the data coming with the creation of the first index is duplicate. The data that comes later to the relevant index is not duplicate. It comes as it should. The problem is only with the data that comes when the first index is created.

When we looked at the indexes written before the upgrade, we did not encounter this situation.

What could be the problem? How can we solve it?

Thanks
