I had the exact same thing happen, it looks like the 6,8, and 9 keys are linked to this glitch in some way, as it was the same on mine. However, the more I re-unlocked my phone, more bars appeared elsewhere. After about six times, I had a grey bar under the 0, 1 and a few apps on my home screen. I will post screenshots when I figure out how 😅
