I have run into an issue in the ArcGIS Pro Catalog Contents pane where feature classes are not shown. One has to select the folder or Feature Dataset and then view any feature classes (if present) in the main Catalog View section. This is very frustrating as it becomes very easy to miss data and is more cumbersome to manually search through a series of folders looking for a feature class. It also is a reduction in functionality from ArcCatalog (something which ESRI seems quite capable of doing). The issue is not present with .TIF files. I have only seen it with feature classes within a fGDB (the only kind of GDB we use), shapefiles, and tables. I noticed this issue first with version 2.4, but it has continued through version 2.7. The strange part is, when searching the same folders and fGDBs using the Catalog Pane (defaults to viewing on the right side of the window), the files and feature classes show up and feature datasets can be expanded just like in ArcCatalog, but there isn't a way to preview or look at metadata in that pane. I have taken a few screenshots to illustrate my issue. Anyone have any ideas?

ArcCatalog, looking at the same fGDB
ArcGIS Pro looking at TIFF file, no issue here.
