This is a known issue, we have resolved it in dev and it will be fixed in Skuid’s Winter 15 release, and probably an upcoming patch release of Skuid Summer 14.
This will be fixed in patch 5.21.6 of Skuid, which will be pushed to all orgs on the 5.21.x branch at the end of this week. If you are not on this branch, go to the Skuid Releases page and install the “Dreamforce 14” release.
