Given the headers/columns, this is the gateway’s Traffic page.
For some gateways (or: packet forwarders?) the gateway’s Traffic page does not show the orange Join Request items (but only the green Join Accept messages, if the gateway was selected to transmit that). Or maybe the orange Join Requests are only shown in the gateway traffic when not accepted?
@dhclark18 did you click those Join Request items to check for more details?
When looking at the application/device’s Data page, the orange Join Requests should also show the assigned DevAddr.
