random "world" showing up in my worlds tab??

Hello,

My server has had the same world for a few weeks now, everything went fine, (besides from a buncha lag sometimes)

until today.

I wanted to log in, I changed nothing in the settings, just started it and joined. It spawned me in a completely new world, no inventory and anything.

I went off and realized that in the "worlds" tab on aternos, it said "world" instead of the original world name (1_15_2_w_zee). also had world_nether and _end

BUT (!)

my original world is listed there TOO. Is there a way to delete the "world" ones?

I'm playing on PaperMC 1.15.2 and currently with no plugins (using it since last yesterday, trying to resolve lag)

if yall have no solutions, i could delete the world and reupload it, i guess *shrug*

but i'm still curious to know what caused this and how to get rid of it.

Please check again now.

This probably happened because of your freaking world name, and might happen again due to this.

We recommend to keep the world name default if not really needed to change it

it's gone, thanks!

the reson i changed the name to that is to know what the world is. After 4 or so years of using aternos, i have a bunch of worlds named "world" from backing up- so it got confusing.

also had some with long names (but i've never had this problem before).

but thanks anyway, will keep it in mind!
