My navigation has always had a weird quirk with showing Charging Sites. If I set a route to a destination, and in-route charging is required, it will choose one as usual. However, if I clear the trip and attempt to search for that exact same site, it will not appear as a numbered blip. This is the case with zero filters enabled, or with filters such as 300kW or "EVGo" selected; the one that is picked automatically will never appear in results. You can manually type, zoom, "Search this Area", "Around Destination", etc.
The reason this is frustrating is because there are multiple automatically-selectable sites along the route, and I know exactly which one I want to use. But because we cannot set an Arrival SoC, we have no control over which sites are chosen. The only way I can influence its decision is by having a particular SoC window. As a workaround, I often just click Remove Charging Stops and manually add the gas station (Flying J, Shell, etc.) so I'll see the correct trip estimates, and then try to remember to Precondition at the right time.
May not be directly related to what you're dealing with, but it does concern missing charge locations. Hopefully 3.0 will take care of this stuff.
