How to cleanup Photo Manager Pro files at iTunes

Hello,

I tried to upload complete folders via iTunes to my App "Photo Manager Pro" on my iPad mini.It did not work,you can only upload the pictures.

But now I have this folders in the list of PMP at iTunes and I

can not extinguish them.

The other problem is, thins an update of one of the programme the pictures exported with PMP from iPad to iTunes now in an folder "export" on iTunes.

I can secure the folder on my Mac,but I can not extinguish die pictures in this folder on iTunes.So every time I transfer pictures the bin added to the old ones and at every transfer to my Mac I have to cleanup the old Pictures.

I think when the first problem is solved,the second one will be solved two.

Does anyone knowns any solution?
