i create an index set.  
prefix sha  
i set the Index rotation to size with Xgb  
and the index retention to delete  
it starts with sha\_0  
reaches the limit of XGB  
creates the sha\_1 index.  
but i still see the sha\_0 with an option to delete.

What’s the full configuration of your index set?  
There’s also an option to specify how many indices to keep.
