Some Navigation Aids not showing on map

Hi, hopefully this is the correct forum and some of the more educated on the forum can assist me with my problem. I am using Mapsource, (I know it has been superseded with Homeport) to created waypoints of my local waterways. The markers used on the water are the red/white navigation symbols. Attached is the pic of the Navigation Aid symbols in Mapsource. My problem is that 1 of the symbols shows correctly on the map, the other, (marked with a red X in pic 2) does not show. It reverts to a square black dot. BTW, I am displaying the map and waypoints on a Garmin GPSMAP 2010C chartplotter.
I appreciate any help.

 

Thanks

Thanks for quick reply @Nuvi-Nebie. It displays OK on PC in Mapsource but it doesn't display on the GPSMap 2010C or GPSmap 292 screens. I will have a go with Basecamp to see if I get any joy. BTW, This is a marine application I'm using.

 

No, the symbol has never appeared on the GPSMap 2010C or the GPSMap 292. I have even tried it on a friends echomap 50DV to no avail. I have even tried it as a custom .png waypoint symbol. I agree with your assumption that the symbol is not compatible with these units. But I'm at as loss as to why one of a set of two similar symbols doesn't work ? I'll try and see if I can get an answer from Garmin!!!!!!!!!!!!

 

Thanks for your interest in trying to resolve my problem @Nuvi-Nebie. I had checked the waypoint symbols in the device menu. Strangely, the Red-White symbol that shows on the device is not included in the menu nor is the one that is not showing. Work that out!! I have also tried different custom formats and no custom symbols show either.

 

Just to clarify; neither of the the Red/white or White/red symbols are shown in the 2010c or 292 Navaids screens. I compile the waypoints using the symbols in the Mapsource 'Navigation Aid'. As shown in attached picture, the Red/white shows whenever I send the waypoints to the devices from Mapsource but the White/red does not show/transfer? Hopefully this explains my problem

 

Yes, I believe I'm flogging a dead horse, (forgive the pun). One interesting point as I said; the red/white symbol is not present in the Navaids 2010C screen, after the waypoint transfer, it shows as a 'ATON, Red White' in the listing. I'm still at a loss as to why the sister symbol doesn't show.
Thanks @Nuvi-Nebie for your time in trying to help me resoslve the issue.
