Hello Vadim,

I hope you are having a nice day.

There is a couple of possible reasons that can cause the error displayed when you try to delete issues.

I recommend you to check if one of the 4 possible reasons in the documentation below is the scenario you are facing:

Cannot reindex jira due to Expected exactly 2 rows the maximum marker row and the lowest ranked row for rank field

Let us know how this approach goes.
