Powered rails become powered after relogging despite there not being any redstone powering it

Steps to reproduce

1. Load MCPE-124291 Rail powering on relog.mcworld

Expected result

All powered rails at Z = 10 should be off. You can see in the world's thumbnail that they were all off when the world was last saved and closed.

Actual result

Some powered rails at Z = 10 are on, some are off. It seems to be random which ones are on. If you break and replace blocks at Z = 11 the rails reset to how they should be powered.

Note: this may have the same underlying cause as MCPE-105749.

When trying to make a collection system using minecarts with hopper and powered rails, i noticed that every time i relogged into the game, a random off powered rail would become on and get stuck on until i fixed it like do in the video then they go back to how they are meant to work by being activated with a redstone torch under the 5th rail (which is the closest powering source). I don't know what is causing it but the redstone is basic and works faultlessly until relogging where the bug happens so i think there is a bug with the game. The video should show everything, that is why it is quite long but i have had to cut areas like writing signs etc and reduced its quality as the file was originally too big but not being a good editor, it is quite rough around the edges as you will see in the video. 

Video contents in order:

• How it should work
• Relogging
• Show the bug/issue
• Quick look at the redstone (even though it shouldn't be the culprit but might be a bug with the redstone and not the rail itself)

If you want the full unedited version, let me know and i will try and respond to you asap as i want to build the farm but can't until the bug is fixed or i can find another way around the problem.

Thanks
