Random light sources in the world

Summary:
Light sources can sometimes appear in the world. They appear randomly all over the world (in all dimensions). Reloading changes the location/removes the light sources.

Steps to reproduce:

  1. Import the world (20 MB) https://drive.google.com/file/d/1vqUcfpiopRLQ91Z_qCTZtqB-1-cd2Nwf/view?usp=share_link

  2. Set the render distance to 10 chunks.

  3. Open the world.

  4. Go around the completely cherry biome you spawned in (until you find the light).
    If not found, reload the world.

  5. Reload the world near the found light.

Observed results:
Light sources randomly appear in the world.

Expected results:
Light sources will not appear randomly in the world.

Notes:
In the provided world, the problem only seems to happen in the cherry biome (and in some previously loaded places like spawn), but in my Realms (1.19.71) it happens everywhere in huge numbers. Realms weighs about 1 GB and the light appears very randomly, so I do not attach it here. If it is also needed, I can attach it. Also, all players of the Realms see the light (synchronously).

I wonder if there might be a light emitting block near Y = 0 where this light appears?

No, this has nothing to do with the Y = 0 coordinate. But it feels like the light is duplicated in some cases.

Issue appears on my Bedrock Server running on Linux. BDS Version is 1.19.73.02.

Having the same issue on our server, Verified by myself and other members.  The lines tend to be in a straight line when appearing. One member said the lines were under her mob farm and completely stopped all mobs from spawning. Which makes me think that its not a visual glitch, but that game actually thinks those area's are lit up.  Verified on BDS multiplayer 1.19.73 server. 

Edit- Verified there are no light blocks present in any of the Y value along the "light".

Also verified there are no light blocks present around 0 x Y x 0.

First screen shot is directly below the lights position.

The second is directly above the lights position.

Affects 1.20.30.22 preview and 1.20.15 hotfix

This bug persists and has gotten worse with the 1.20.30 update.

Save The Bedrock

It concerns version 1.20.50 on my realm

Lighting bugs still occur quite often on my world, although they are not lines, but regions of bright areas in closed rooms.
