Sort Query Not Working

[Deleted user]

I'm displaying Jira issues on a Confluence page as a change log for my team.  The Fix Version field is populated with YYYY-MMDD and I'm sorting on that field to see the most recent changes first.  My query is:  

project = WPS AND fixVersion is not EMPTY ORDER BY fixVersion ASC

Most of the issues are sorted correctly, but out of 75 issues in the list, there are about 20 that are out of order.  Interestingly, the issues that are out of order are grouped according to the data in the field.  So, if 2018-0122 is out of order and there are multiple issues with that Fix Version, they are all grouped together.

Any ideas?

Thanks,

Stacey
