Hi Kevin, thank you, I just submitted a ticket.
We haven't heard of that issue, but now that you mention it I see this is an issue. The bottom update button does not appear to be functioning. We have a programmer working on some other Immunization changes right now, so I'll mention this bug to him as well. Please also create a ticket for this issue with Support so it can be properly diagnosed and logged.
We notice that, when changing fields in the Immunizations page, the Update button at the bottom of the page does not initiate a save; however, clicking the Update button at the TOP of the page does initiate a save and close the fields properly (as a work-around). Is anyone else experiencing this problem?
