RTO India — Duplicate number plate of my vehicle found in Fines

My vehicle number is KA01JH9729 (Suzuki Access). I have registered this vehicle in 2020. I received a notice from RTO for driving vehicle without helmet. When I checked the image from website I found different vehicle with same number plate. (TVS: Jupiter). Can same number be allotted to 2 different vehicles? I have my vehicle documents with me. Request you to please check attached snapshots of the image. snapshot of Suzuki Access vehicle is mine and the other snapshot Tvs Jupiter vehicle with 2 people is which I received notice from RTO for penalty charge is not mine.
