[Plugin: EG-Attachments] Sorting of attachments is arbitrary

I’m using EG-attachements and I can’t get the sorting to change, no matter what I change in the settings. I’ve set the plugin for activation ‘at the end’ and to sort by title.

But whatever I change in the ‘order by’ option doesn’t seem to have any effect. The used order seems to be the upload order or something arbitrary.

Thanks in advance..
