Many thanks for this posting!
Within the producer's information tab, SureLC does include validation checkmarks for each tab. For the situation described above, the problem was that a "blank" signature page, and hence, a "blank" signature image, was included as part of the contracting paperwork.
At this time, when a blank signature page (and thus, a blank signature image because the producer didn't sign the page) is uploaded into SureLC, SureLC doesn't make the distinction between a 'blank' signature image vs. a signature image that was provided. This is by design (see the last entry on this page: https://surancebay.zendesk.com/entries/40867120-Producer-Setup-Packet).
If there's any other validation issues/problems within SureLC - we cordially request all of our users to post their comments here so that SuranceBay's IT team can work to resolve them.
