2018 R1 faulty brake power indicator on the dashboard

Hello guys, I've just happen to encounter this weird behavior on my 2018 r1. The braking power indicator on the dash starts at max value while no brake are applied. I can move the bike freely, I cannot feel any braking from the front/rear wheel. I tried to ride it around the block to test if everything works fine, the abs is working on both wheels. The indicator seems to get back slowly to min value after a while. Once I remove the key and put it back on the problem seems to happen again. Any idea on what's going on ? I recently changed the brake fluid could it be the cause? Thank you!
