Hardcore and SSF Stash Bug(s)

So, I may not know how this is supposed to work, but I was under the impression that every Solo Self Found character started off with nothing in their stash tab. I also thought that when a hardcore character dies, they end up joining their parent league.

On console I stay in the Standard league.
- The first character I create in Hardcore/SSF has nothing in the stash tab. I progress through the game, stash stuff in the stash, die, darn, delete the character.
- I create another Hardcore/SSF character. I progress through the game, stash stuff in the stash, but then start playing POE on the PC and leave this character alive.
- I come back to console, start a new Hardcore/SSF character and find that I'm sharing the stash from the currently alive character that I didn't delete.
- So I intentionally die with this third character and then find I'm sharing the stash with the first character that I created and deleted after they died.
-(Migrating the character from SSF to Standard after they had already died in Hardcore did bring them back to the proper standard stash.)

Sooooo, I'm not sure what the bug is specifically.
- SSF characters can share stash tabs with other SSF characters?
- There are alternate SSF universes?

It was kinda confusing, but I guess the bug is maybe double check if Hardcore and SSF restrictions are acting properly?

Sorry to bother you if everything is working as intended.

This is incorrect.

Your stash in each league is shared by all characters in that league. SSF Leagues prevent you from grouping up / trading with other players, but otherwise function just like any other league.

So I can stock up a SSF stash with previous characters?
