How to best handle this series request?

[Tami]

Hi fellow librarians,

I need some help with this request. I answered this request about a series that is having numbering problems: https://www.goodreads.com/topic/show/...

The "full volumes" were first published for free on the author's site as a web serial according to the series description. They were later published through Amazon and Audible with a slight different numbering as can be seen on the covers. There's more context and longer explanation in the thread.

My question is should the series stay as it is. I fixed it for now to have the split editions at the bottom because a librarian had listed them in between each full volume. Or should we fix the numbering as it is on Amazon https://www.amazon.com/dp/B099JFQ9YR with the webserial volumes as omnibuses (books 3-4, 5-6, etc) or it is fine as it currently is?

Note: I thought to add that the series being published on Amazon appears to be ongoing and not finished. I don't know about the web serial.

I really hope someone could help with this!
