Issue: Select by Features Attribute Table has more rows than input feature

[EricAlbers1]

Hi there,

I have been experiencing a strange issue with ArcGIS Pro selection tools lately.

I start with a layer of Census Blocks and use the tool to create new layers of successively smaller numbers of blocks.

Lately, I have run into an issue where I will have a layer with say 172 blocks then use Select by Location / Attributes to further refine the layer. The resulting layer will have more blocks than the original input layer (photo attached). Does anyone know how I can address this?

version of Pro?

what is your selection query? and

just to check, clear the selection between selections to see if it persists.

I would report it if you suspect a bug...it won't be addressed unless someone reports  it and it can be verified

So are you using a Query Layer or Database view at all?  I'm seeing some cases where there was duplicates being returned via the view.  Also there is BUG-000125909 - The Select by Attributes tool displays incorrect selection of records on a database table without a Unique ID field. But this was fixed at ArcGIS Pro 2.8.  What release of ArcGIS Pro are you using?
