Emergency Exposure Management: When a company becomes aware that an employee has been diagnosed with an illness, this workflow helps the employer identify other employees who might have been exposed based on the employee’s meeting history and location.
When setting the Start & End Date perimeters, we should expect the bannered message saying 'Select the Start & End date' to either feedback a confirmed message or to go away, but it doesn't. You can save the record and selected Run Diagnostics and still the message will remain. This message is cosmetic and the selected dates have been updated.
Currently there is no workaround for this issue, however functionality is still working and the message staying on screen is only cosmetic.
There will be a fix coming out on the next release.
