Question about Projections

I have a pretty simple question about lining up data correctly.


I have a data frame that is using the coordinate system srid = 4326. I went to the SDE source and changed the XY coordinate system for 2 feature classes to 4326 as well. When I add both to ArcMap as layers they are not on top of each other even though the XY coordinate system and data frame coordinate systems all match. Is there any guide or clues as to what the issue may be and how to resolve it?


One of the layers is a SQL Query Layer and the other one is coming from SDE but the issue is that if I have set all of the coordinate systems to match, why doesn't the data line up?
