In version 4.7 of Importacular, a bug that removed specific address line mappings has also affected the functionality of the Criteria Sets to match data in import data sources to data in Raiser's Edge based on the Address 1 field. All other Criteria Set options are working as expected and this issue is resolved in version 4.8 (due to be released in Q1 of 2021).
For versions later than 4.7 with this issue, we recommend that you review this knowledgebase article about changes you can make to your Criteria Sets to improve your matched records.
