Members Count on Work

When does a member count as a holder of a work? I would like to know why Members shows as zero instead of counting my edition in the work linked below.

>1 aspirit: It was a zero copy work. Try this https://www.librarything.com/work/23921306

Does that mean the Main page was linking to a previous version of my edition?

ETA: I think there's a bug. The work is now showing a count of two reviews for my one review, which is only appearing once in text. I'll take another look after a break before going to Bug Collectors.

Chances are you amended something in the title or author when you entered it. The first version would have become the zero copy edition after the amendments and the updated edition is the one that stuck. Zero copy editions never disappear from the system they just lay low for awhile. I can only see 1 review there, I suspect if you give it a bit of time to settle down it should be alright.

There are several servers, and things can update at different times. Things like this just after changes usually clear themselves if you don't keep trying to fix them.
