Wrong Directory for Uploads

Love the plugin but I stumbled across a very strange behavior:

Everytime I’m trying to upload a file via a repeater field and use the same file twice for each repater row, the first file will be correctly uploaded to the uploads folder, but the second file doesn’t. But whats even more strange is the fact that after saving wordpress thinks that the file of the second repeater row is in fea-submissions folder. Wouldn’t be to dramatic, but the file doesn’t exist in that folder, so I get an error…
