Listings going to drafts

I’ve seen a few threads on this issue but nothing that has resolved it for me.

I’m finding that each day more of my listings are going in to drafts, some haven’t even expired yet.

Even after i re-publish them, the next day they are back in drafts. This is quite a big issue, especially with some of them still live.

Can anyone shed any light on this issue?

Thanks in advance.
