I see 3 as well, like Nyaa. I think you have federation turned off, as I only see 1 then. On the sidebar, click the fediverse icon (the 3 dots connected by lines, next to the cog wheel), check if Status is off, and if it is, set it to On.

Edit: Although perhaps you might not want it on, in which case that could be a bug. If that is what's happening, I can have a quick look to see if there's a bug in the issue tracker and if not make one for the number not matching federation status on/off (though not sure if it's possible to fix or not, I imagine it would also be inaccurate based on other filters as well)
