Removing a starter does not ask which starter to remove
If i add 2 starters to the panel and then right click one of them to remove it i get asked if i want to delete "Starter".
But just looking at the dialog there is no way to know which starter will be deleted.
Perhaps it would be more interesting to ask if you want to delete e.g. "HexChat"/"HexChat starter"/"HexChat Starter" or whatever the starter is called.
Just like when i try to remove a panel plugin it doesn't just say if i want to remove "Panel plugin". It says if i want to remove e.g. "PulseAudio plugin".
