Not really a bug, but the female Sawsbuck Pokemon have antlers when they are supposed to have none. In addition, the male Deerling model does not have antlers when it is supposed to. My girlfriend is very concerned about this error and she says that she will leave me if you do not fix it. It is to my understanding that the female and male Pyroar Pokemon have different models, so I know that this is possible for the modification known as Pixelmon Reforged. Please do whatever you can to rectify this. My girlfriend is very special to me and I would hate it if she left me over such a minor detail in a video game. Thank you for taking the time out of your busy day to read my report and I hope you have a blessed time in quarantine. <3

Your girlfriend's memory seems to be wrong. Female Sawsbucks have antlers and male Deerlings do not.

Nice troll bug report.

Deerling doesn't have antlers. Sawsbuck does.
Also:

"My girlfriend is very concerned about this error and she says that she will leave me if you do not fix it."

????????????? If your girlfriend leaves you over deerling not having antlers and sawsbuck having them, then your girl is not the right one for you, chief. LOOOL

Closing this as not a bug. Above two comments are correct. I'm not sure where you got those facts from, but male and female deerling/sawsbuck do not have any gender appearance differences. Deerling does not have antlers, and Sawsbuck does, regardless of gender. I'd recommend doing some research before posting a report like that.
