I've observed for a while that for many (but not all) of my tables, QGIS 3 (2.99) shows the same table name twice in the Browser Panel on the left, when I expand my PostGIS data source.
The first entry in the Browser view can be loaded into QGIS normally, but the second instance gives a
Coordinate Reference System Selector dialogbox and once loaded shows no data at all.
Does someone know why this happens and is it possible to not show the 2nd entry?

everything's fine in browser panel
