This is common when Users are importing statuses from another statusing software - they run the import weekly, while there may be multiple status updates against the same resource in the past week, and they don't have the data of when the update was recorded (or they were recorded on the same date).
For example, SYNCHRO fails to capture "Erected" because the status date is on the same date as "Detailed", and "Detailed" takes precedence. (As shown below)
However, if the dates are stepped out both statuses are imported successfully.
Would be great if this limitation can be removed.
