Random dim of lights appearing in my realm world

Hi, I own a realm and just yesterday I started having this issue and I'm not sure how and why it started randomly across my world Dims of lights just started appearing across my map and I'm able to get rid of them by placing a block of the dim of light but every time I do it after I leave and rejoin the world it appears back and it's scattered around my world and lighting up ares.. I made it night and mobs still spawned in the lights i assume it’s a visual glitch. I also got my friends to join and see if they see what I see they are all in console by the way and they saw the light dims but they had different patterns and were in different area were I wasn’t able to see it. For some reason when I use my iPhone the light dims aren't even appearing I assume it's a console issue I even bought a new realm on my console to see if this was true and it was the light dims started appearing in my new realm as well so I'm not sure what I can do.
