This is a known issue - when manually importing recurring gifts through Omatic Cloud the Next Transaction Date does not populate. This is wildly important information and frustrating that it's a Sky API issue and not something through Omatic. Please fix so we have these solutions when DBV is sunsetted.
See Omatic Knowledgebase for more information: Issue-Next-Transaction-Date-Fails-to-Update-after-a-Payment-Is-Imported-to-Raiser-s-Edge-NXT
Thanks
