While trying to edit/update a hosted feature layer I got a warning:

After checking the properties I found multiple Spatial refecences:

I didn't know this was possible. Looking at the fields I see a small mess:

 4 shape length fields, hmm. Some of the data is collected using Collector, other might have been copied using Pro.

Does anyone know on how to clean this, resolve the multiple Spatial Refecences?

Thanks in advance for your time.

 

Regards, Bert

@BertKraan1the second coordinate system you see listed there is the geographic datum.  Each projected coordinate system will have a geographic datum.  So, this is normal what you're seeing.

The multiple shape_length fields your seeing are most likely from multiple copy/pastes or export/imports.  Only one will be updated, and you should not be able to delete this field (if the data is residing in a geodatabase).  The other shape_length fields should be able to be deleted.
