Can't Delete Fillets

Hello. I’m having trouble deleting a couple of Fillets on a part I designed in shapr3D. I keep receiving the following message, “The face can’t be deleted because the resulting hole in the body can’t be filled.” The fillets aren’t around any holes though. Any ideas on how I can get past this message and delete the unwanted fillets? Thank you.

Hello,
You may have to remove some connected fillets before removing the desired ones. The meaning of the error message is there would be a hole in the body if removing your selection would be allowed. It happens regularly if there is no remaining edge that could be rebuilt after deleting the fillet.
