Weather plasmoid keeps disappearing between logins

I keep adding a Weather Report plasmoid to my bottom panel, but every time I login it’s gone.

It’s not that it’s invisible or something. If I add it again, the instance count is 1 and the plasmoid remembers all its settings.

Also, this seems to only happen with the weather plasmoid. If I add any others, they do remain between logins.

EDIT: At least it used to remember its settings, I just added it again and it’s forgotten them. Perhaps because I didn’t re-add it in the previous login?

EDIT 2: Forgot to say, using Plasma 6 on Neon, fully updated at this moment.
