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?
