On EAD import, controlaccess/title tags are not being imported into uniform title Subject objects. The EAD file imports successfully without obvious error, so the issue was only found via QC.
Dev. Pri. Recommendation: Move forward with development
Tested this in the hosted version of AS Test. Imported an EAD file with a subject with a uniform title type and it worked appropriately.
Tested this AS Test. Imported File (Index Seminum Collection) displays <controlaccess>/<title> correctly in AS Staff UI.
