Problem : slug is being update every time we uploading image !!

Hi there,
I have been experience this issue as I am new to NextGen Gallery and how its functioning.

The issue is that every time i am trying to upload images the slug name get replaced by the gallery title ?!!

this is hapening through NextGEN Gallery Admin

/wp-admin/admin.php?page=ngg_addgallery

And choose the Upload Image option and selected an existing gallery from the dropdown list.

After the images have been uploaded under that gallery name, for some reason the system changing the value of the “Slug” field of the “wp_ngg_gallery” table and replace it with the same name in the “title” field !!!

Example :
==============
Before uploading the images the value are:
slug = “1234”
Title = “Test”

After uploading the images are:
slug = “test”
Title = “Test”

as I am having custom slug name. why the script keep changing this field every time I am uploading images ?!!

This is really annoying issue as i have to change the slug of the gallery after eash single upload. which is very strange and outside the normal practice for such plugin !!

Appreciate you support to get the fix soon.

Regards,
Badar
