Additional Information
The provided case is not a 1:m cardinality join; rather, it is a 1:1 join, as the join table's UniqueID field contains only unique values. If there were duplicate values in that field, it would result in a 1:m join to the same value in the input table's UniqueID field, and this would be reported as such when using Validate Join. However, that is not the case.Steps to Reproduce
