General Support: Default sort order broken??

Hello

I use Version 3.0 Beta of plogger and i got a problem. all the images from my camera is named DCMXXXX so let's say 3 images taken after each other would be named "DCM0001,DCM0002,DCM0003" and so on. after i uploaded these 3 images to plogger i went into the admin section of plogger and scrolled down to "Default Sort Order:" and i choose "Filname" and then "Ascending" and save. but when i then go into the gallery where those 3 images are they are scramled in the order "DCM0003,DCM0001,DCM0002", Why wont plogger sort them in order ? is the "Default Sort Order:" function broken?

I have selected a sort order based on caption and have given my images a caption of "a) Some Text" and "b) Some Other Text" and the order doesn't seem to work either. Has any one else found this?

Thanks
Janice
