I'm seeing the same post from the same user posted in the same community but it seems to be delivered from multiple instances. I have the show all option turned off. Can't figure out why I'm seeing multiple, a good example is when you sort by top of day and you'll see a lot of duplicate post grouped together.
Edit- turning off the see all seems like it essentially forces it to local only, which sorta fixes it, but that's not what I want. On Jerboa for example, I can filter by all (multi instances), and only see one example of each post power community
Edit 2 - so it's something to do with using the 'see all' from multiple instances, even ones your not part of. The problem is it's don't the duplicating there, but seems to be for the same community, but something is of in the parity. For now I'm just using [email protected] and that seems to be better for now
Here's what it looks like if you go to Lemmy.world directly
