Attached Screenshot shows Pearl Harbor with Aviation Support 454+40.
Destination screen (Pearl Harbor) shows 227.
Eng support total is 177 and HQ support is 50.
Both add up to 227.
40 Aviation Support is provided by Tenders.
So where does the value of 454 come from?
EDIT: Transfering planes from San Diego to Los Angeles shows the same effect.
Los Angeles shows 248, the destination screen (from San Diego) shows 124 which is in line with the only Eng unit at Los Angeles (Los Angeles Base Force).
