Did my agent try to sneak this past me?

Our potential listing agent has been our buyers agent twice. We really liked her the first time so we used her again, and that time was not as great as the first. I let it go and we decided to use her again to sell.

We moved in 3 years ago and our life has changed dramatically so we are selling. We don’t want to lose money but we know it’s a real possibility so I asked her what’s the best she could do on commission. She told me 4% (so 2% and 2%) unless she can do both sides, then she said she’d do 3%. Again, I just dealt with it and assumed she was doing the best she could but when she sent over the contract, she put 4% to her broker and then checked the box that said seller authorizes broker to offer 2% to buyers broker at sellers expense (so 6%). There was also a mistake where she checked that we didn’t authorize it listed on the MLS. Now it absolutely could have all been an honest mistake, but she’s thrown so many numbers at me and knows I’ve never sold a home before and that I’m very busy and distracted with a baby. So I’m a little wary.

Am I overreacting? My neighbor is a realtor who actually was the sellers agent when we bought and we’re considering asking her to list for us instead.

Edit to add: she also said the reason she couldn’t do any better on brokers fees was because he just bought a 600k dollar boat and now they’re all paying for it (I’m paying for it??) my dad also suggested that the commission she offered wasn’t a favor.
