Yes, removing the old DataCenter*.xml files from the /appdata/OneView/MyReports directory should resolve the issue.
Or You can just re-name each of the DCM files in case you want to keep a back up:
For example, mv DataCenterManagerAllHypervisors_IA.xml DataCenterManagerAllHypervisors_IA.xml.BACKUP
You may need to "Refresh" (F5 button) the OneView Reports page in order to update the browser cache.
They have fixed this in later builds yet to be released...
