Odd Powered Rail Bug

So I'm having fun in my 5-year-old rollercoaster world (placing a ton of minecarts), and some get stuck, no biggie. I break a block with a redstone torch nearby, and all the minecarts fall, but when I place the rail back, it isn't working. The torch isn't powering it or the rail next it! Tested it on the ground and everything was fun. Please fix this soon. I finished this rollercoaster years ago, and I can't seem to get the rails back to normal no matter what I do. Please fix this odd bug. Screenshots are spots where the torches should be powering the rails. Any suggestions on what I should do?
