Seal tyre pressure swapped after recent upgrade?

Hey guys As the title suggests, for some reason the tyre pressure on the left hand side of the car (passenger side, UK) have swapped for front and back. Ive tested the tyres and topped up air etc but its definitely the sensor. Does anyone know of any solutions I can try before going into the dealership and spending a whole day Thanks Apologies not sure why I can't upload an image so here's the link: https://photos.app.goo.gl/yZXMHfnYZBxJTTTF6
