My Collection has disappeared

Hi, I added new coins to my collection and noticed it only said 34 coins. I have over a thousand coins that were in my catalog. Has something happened that Ive missed? I dont know where they have all gone.

Does this show at the top?

You have everything set completely to private so I can not even see your numbers but usually this is due to a filter setting.
Are your filters set to ‘All/ collections/types’?
