I get this message for datasets in ArcGIS Hub which comes from the ArcGIS Server. I tried to zoom but no objects appear on the map and the message does not disappear. I can only see the extent of my layer as marked on the picture below:

I have tested one feature layer which has only four rows. It looks fine when the layer is hosted feature layer in AGOL, but when I use the same layer as a reference from ArcGIS Server (10.7.1) in AGOL I get the mentioned message.
I have also noticed that layers which show this message miss the "rows" attribute, while the others get this one populated:

Is it expected behavior or can I change some settings in order to get the objects on the map in Hub?
I will appreciate any help!
