Sounds like you need to be a bit more proactive with your bonding. If I was in your position this is what I would do.
1. Give a cool off period allow for healing and give the bunnies some space. Bring them out individually for play time and try not to allow them to mark territory ad best as possible to keep the space neutral. This could be at least a week or two.
2. Prepare yourself for bonding. There are many ways to bond rabbits. But one thing that is ever present is that the space has to be 100% neutral like a bathtub or on top of your washer/table somewhere were both bunnies do not go. Prepare a large dustpan or a thin piece of plywood to separate them completely. water will not work for your bunnies so you will have to use physical barriers. Gloves are a good idea in case your bunny bites you, get some heavy leather or snow gloves.
3. Prep two seperate cages like nic grids that are focused on letting your bunnies meet eachother. I would do the box cube method as this allows them to be focused and can see eachother and smell eachother without touching eachother. Make sure these cages are 3 inches apart so they cannot bite eachother but can get close to some degree.
4. After a few first meet and greets I would do a cage swap, make each bun occupy the others space and let this happen for a day. This allows them to realize that another bunny has been in their house and it’s ok. Keep dpi g the social dates with the cubes.
5. After a few swaps and treats and their flopping or grooming year eachother a meet is now in order. Get your gloves and ply wood and take your buns to the neutral space. If your putting both buns in a box or crate use a dust pan, and at the first sign of agressive behavior like lunges or sudden turns towards the butt or face put the barrier firmly in between to reset the mood. Do this for about 30 minutes and offer pets and good vocal encouragement. If any injuries happen that draw blood. Stop immidately as that session will be all defensive and not helpful.
Optional: some owners do not like this but you can stress bond your bunnies when you hit the meetup stage, placing them together on a washer with a towel under their crate or driv8ng around with an extra pair of hands around the block will bond them under stressful circumstances.
6. Repeat steps 4-5 until you see positive behavior such as grooming or flooring next to eachother these are good signs your bunnies know that they are friends.
I would suggest watching videos from 101rabbits or stormyrabbits on bonding, stormy rabbits had to do an agressive bond so lookup her vlog video to see what she did bit always do what’s best for you and your bunnies.
Good luck
