Cannot delete page [[card]]

Hello, I’m very new to Logseq and this forum. I seem to be unable to post a new topic so I’m replying here in the hope someone can assist. I have the Logseq sync feature enabled and for all intents and purposes it’s working fine. However I have a persistent ‘page’ that I cannot delete. It’s on all my devices. It’s called ‘card’ and is in faint text. Any ideas how it can be removed? I thought maybe it was like the Contents page and needed to be there, but I can’t find anyone else talking about it when I search for the issue. I’ve tried placing a screenshot in my reply but the forum doesn’t seem to want to let me do that either.

I think it’s used for flashcard feature.
In my graph is present a page called “card” I have never edited.
