Thanks Jason - it was version 1.1.3
I've been trying deleting those files - I've deleted the entire /email/ folder from the remote server, deleted those two from my local machine and edited the UE behaviour without making any changes, and reuploaded the entire /webassist/ folder and emailCandidates.php pages.
It did look promising, as in the server behaviour box it did have (prior version) next to the UE behaviour before I edited it, and was gone after I edited.
But unfortunately nothing looks like it has changed.
