Trying to reconnect Logseq device, finding myself baffled by naming of graphs and folders on multiple devices

I am very confused when my three devices go out of synch and then I need to reconnect and there are local files. And then there are graphs. And then there are multiple devices that repeat this.

When I’m setting this up I must have named things very very poorly and been even more confused than I am right now. Because I am looking folders within folders that have the same names like ‘Logseq’ or Documents?
Can I rename this?

How can I reconnect on the ipad?
AND TO PREVENT THIS AGAIN how can one rename these folders and graphs (already being used by my 2 other devoces) in a way that it’s less confusing and nested?

Please help.
Thank you.
Peace,
