There is https://github.com/jmvedrine/moodle-qtype_ddmatch/commits/master
I don't know why it is separate repository. And I had not time to add these changes into my repo. I was planning to address this issue in the summer when I will upgrade to the Moodle 2.5.

yes, thanks. I found it, but it looks different.
May be a cache issue I can resolve.
the css might be cached some where in the moodle 2.4 dungeons... ;-)

We had the same issues.
After adding https://github.com/jmvedrine/moodle-qtype_ddmatch.git
as new remote and using his master branch, Issue was solved :-)

Please see if you can pull fixes from his repo.
