Unable to remove pins from Maps on macOS Monterey

I use maps to work out delivery routes. When the route changes, I need to add and remove pins. Presently, I am unable to remove pins from my maps. If I highlight the pin and use the drop down menu, there is no option to remove the pin. If I highlight a pin and wait for the info box to come up, sometimes there is a remove option with a trash icon. Doesn't matter as it doesn't work. I have also tried removing the location from the guide. Same. I have restarted the app and restarted the computer. No change. CTR-click does not work either. Ideas?
