Link to a page where the issue can be seen: hidden link
I expected to see: toolset-post-sortorder as a selectable option in the Order by dropdown
Instead, I got: An option that shows "Field - ", but toolset-post-sortorder is missing
It's worth noting that this issue does not happen on a localhost version of the site (separate install, sandbox version. Toolset CPT, tax, fields etc were created there and then exported and imported into the site on the domain). The export/import may be causing some issues, not sure.
