Player takes fire damage on blocks that previously been on fire from the flint and steel item. For example. I came across this because I was burning down some trees. The only way I was able to stop myself from catching on fire and fixing the glitch. Was placing a block on top of the block that wasn't on fire yet damaging me, then placing a water bucket then picking the water back up and removing the block on top of the original block that was catching me on fire yet there was no fire on or around it, but was previously on fire from the flint and steel because of the trees. This also occurred when I was building up. I would be burning fast when I'm not exposed to any fire. Something I did keep in mind was the tree I burnt was in that exact area before so my theory is there's invisible fire blocks damaging me which is obviously a glitch. That can only be fixed if I do the previous method I explained. I even died many times just testing the glitched block. I am experiencing this on my Xbox One on bedrock edition. I even got friends to witness me catch on fire and die fast when there was no flames on site. I was messing around with fire spreads at the time so it could relate to that. Not sure if others are experiencing this but I thought I'd share my gameplay experience as it does not seem natural for that to happen in game.
