Description

PDU Power outlet sorting is different in PDU Device view and when selecting the power outlet when connecting a device to the PDU.

For example;
P1-C13-[1-13]
P1-C19-[1-2]
P2-C13-[1-13]
P2-C19-[1-2]
P3-C13-[1-13]
P3-C19-[1-2]

This is shown in the device view as following: https://imgur.com/yMRcQfJ
while when connecting a device power connection to the pdu the sorting is as following: https://imgur.com/c1cGuBb

Expected behavior would be the same as in the device view, that has P1-C13-[1-13] first, followed by P1-C19-[1-2] and there after P2 and so on.
