Image Rotation Mismatch

Been using this plugin for afew days only, it is amazing and exactly what i needed. However i am experiencing an issue and couldnt find the answer online.

When my images have been uploaded, some of them rotate incorrectly on the “Manage Galleries” page when editing a gallery. The thumbnail image vs the full screen image are set at two different rotations for some of the images. It seams random and intermittant.

This also shows on the live website. The images show different rotations in slideshow mode as they do in thumbnail mode.

Anyone had this issue before or have any ideas what could be wrong?
