3rd Party Presets not showing up under Bankname

Hello
I am sure their is a simple solution to my problem but I cannot solve it myself. I purchased a 3rd party sound bank and am having problems getting Absynth5 to see it as a Bankname (my bankname list includes absynth4, absynth 5, absynth legacy, spectral expansion and absynth twilights).
If I click on the sounds tab in Absynth it changes to File Explorer and I can see my 3rd party preset under absynth twilights.
I put the 3rd party presets pack here :

C:\Program Files\Common Files\Native Instruments\Absynth 5\Sounds

When I rebuild the database using the standalone Absynth it adds all the other banks apart from my 3rd party presets

Am I doing something wrong?

Thanks

 

Maybee the 3rd party builder forgot to set the name in?

 

Yes I think you may be right as have had a look and no author or bankname seems to have been set in the preset attributes which is a pain
Not sure if any option mass adding attributes?

 

Write one in and save again - right?
