Multiple Rows checkbox not working

[nikjdwhite]

I'd like for some of the fields (such as Description) to display as a textarea in the user-end form and others (like Creator) to display as a single-line input. According to the docs the Multiple Rows checkbox in the admin interface controls this display. However, on my Omeka site the checkboxes are all marked on the admin side, but all fields display as single-line inputs on the user end (screenshots below). If I uncheck any of them and save, the unchecking doesn't stick and they revert to all being checked, with no change to the front end.

So far I have reinstalled a fresh download of Contribution, and deactivated SimpleVocab since that seemed to interfere as well, but it's still not retaining the multiline setting. Any advice appreciated!
