OpenCPN does not show 18603_1.KAP or 18603_2.KAP, because the program can't find the
charts. These charts are nowhere in your log.
Let's backpedal and recheck your downloaded files. Do you have a folder
C:\Users\OSPREY877\Documents\Charts\RNC\US_WA\1860 3 ? Do you have a 18603 folder anywhere else?
If yes. Does the content match this ?
