What is the source of data?
A data source can have a projection but not be projected properly.
One of my early tasks was converting from AutoCAD to ArcGIS. The entire drawing was to scale but appeared on the equator.
You may have to geo-reference your feature that is out of limits.
However before you do that. Start a new session. Add one of the features. The add ESRI base map to the session and determine if the feature is in the correct location.
Then do the same with the other.
If one of them does not appear where it should it is the one that needs to be referenced.
IF both of them individually appear where they should be then you have a bigger problem.
