Game folder value (<Folder></Folder>) keeps getting changed

[jamz]

I'm going through the process of importing roms into LB 13.26.

I've restarted the process several times as the value for the 'Game folder' keeps getting changed which screws things up.

For example, I imported (using Tools / Import ROM files / Import Single Platform) a collection of Nintendo DS ROMs. There are located in  "Y:\Emulators\Roms\Nintendo DS"

It imported these fine, I can see them in the list. I imported a couple more platforms.

Now when I check the Tools / Manage Platforms option, I see the folder for the Nintendo DS ROMs has changed to "Y:\Emulators\Roms". I can confirm this in Platforms.xml:

<Folder>Y:\Emulators\Roms</Folder>

Why does this keep happening? It's not always the Nintendo DS folder, it's happened to a bunch of them. Changing them back works, but then a bit later there will be another platform which loses its folder and is set to "Y:\Emulators\Roms"

This causes an issue because all my platforms are under Y:\Emulators\Roms and then scans start adding thousands of ROMs from different machines to the wrong platform.

Is this a known issue? Does anyone have any idea why it's happening?

Thanks
