Reordering of fields (category, logo, tags) makes problems in output

Version: v2.0.0.17-rc
Genesis Child Theme

When I reorganize, reorder (drag and drop) fields in Places > Settings > Custom Fields, I sometimes get an error = output will not show and the field disappears when I edit an enty.

E.g. if I reorder Category field (do it on bottom in the list), then in output of place detail there is no category field visible anymore (nowhere, not even in the main page). And when I edit the entry the category field is missing as well. Although I didn’t change any settings in the category field, just the order in the field list.

Then I reorder Category field again (put it on top or below description) and suddenly it works again. So there has to be an error in saving the reordering of fields and making problems with the output.
