Safari keeps deleting items from my reading list My safari's reading list is "one shot", in the sense that if I open a URL it gets deleted, so I can just read it once. But some articles are long and I read them in 3-4 times. 

I’d like manual removal only from my reading list using safari on macOS. 

Is this how reading list is designed, that links disappear when you read them?
They're not being deleted, they're just read and you're hiding read items. Show unread items in reading list by clicking the Show Unread button above the list.
