ArcGIS Pro cloned Python environment changes to default

I have created a clone of the default environment in ArcGIS Pro 2.8, and have installed GeoPandas within it. In ArcGIS Pro Setting I activated the clone environment [toggle radio button) and restarted ArcGIS Pro. However, after the restart, the ArcGIS setting Python shows that the default environment is activated. After the restart instead of the clone environment being activated the default is in fact activated.

Any recommendations?
