Severe Issue with ArcGIS Pro 2.2 Patch 2
Esri has discovered a severe issue with an editing workflow in ArcGIS Pro 2.2 Patch 2 (2.2.2) that may incorrectly set feature attribute field values to “Null” and strongly recommends this patch be uninstalled. 

How do I uninstall the patch?  
In Windows, open the Control Panel and search for “View installed updates”; click this option. Right-click ArcGIS Pro 2.2 Patch 2 (2.2.2); and click Uninstall.   
 
What is the Issue? 
Field values may be incorrectly set to Null when using the Attributes pane. This problem occurs when you select multiple features in the tree view of the Attributes pane, use the Tab key to navigate between cells in the data grid, and tab through a cell that displays “(Different values)”.
 
When will Esri correct the issue? 
ArcGIS Pro 2.2 Patch 3 (2.2.3) will be available in October, 2018, and will include a fix for this issue as well as the other software improvements included with patches 1 and 2.
