removing previous owner's association with my airpods pro 2

hi, I bought a used airpods pro 2 from amazon

first when I connected them, they said they are x's airpods

1. I figured a factory reset solution (lid open, hold button till it light goes amber).
   1. now it automatically took my name
   2. let me add it to find my devices etc
2. however, when I go to find my app it shows me the first image attached
3. on icloud it shows me second image attached. Why does it not give me options like erase etc

two questions

1. how to solve first image
   1. i have ofcourse done all the things mentioned in those links yet they are still there
   2. I don't think it's a mixup. Airpods printed serial number for case, L, R are matching the ones in Bluetooth settings
2. If I change name of airpods, will previous owner see the name. Thinking of changing name to [urgent] please remove device
