No "automatically create subcategories" for MAME anymore?

[Dunuin]

Hi,

Right now I'm using Launchbox version 11.2 because without a credit card there is no way to renew my license.
In the past I imported a full MAME 217 set and used that "automatically create subcategories" feature to create genre, players and region playlists.
I now deleted my Arcade platform and created a new one and used "Import -> MAME arcade full set" to import my new MAME 228 set.
But if I right click on the new Arcade platform there is no "automatically create subcategories" anymore. If I right click on other old platforms this feature still existis.

Is there something I can do to use this feature for my new MAME set? 

I know that I can choose at "Import -> MAME arcade full set" to create some playlists but these are very limited and not as detailed as the one I got when using "automatically create subcategories".

Definitely an odd issue since it is only affecting Mame. Maybe something got corrupted. You can try reinstalling 11.2 over top of you current build. It will not change any settings or games. In your \updates folder you should see the installer for that version. Just run it. Make sure it installs to the correct folder. I mention this as some users did not look at the folder it was installing to and it ended up installing to a \Launchbox\Launchbox folder.

I think I now found out whats wrong.
My old MAME platform was called "Arcade" and was child of the Category "Arcades". After I deleted the old MAME platform and all playlists I only got a empty "Arcades" category. Then I imported the new MAME set as platform named "Arcade".
And this created something like this:
Arcades
--> Arcade
----> 2-Player Games
----> 4- Player Games
...
----> Arcade
...

But this "Arcade" is just a category too and not a real platform.
The real platform "Arcade" was hidden inside the category "Arcade" between all the autogenerated playlists.
If I right click on that real platform there is a "automatically create subcategories" available.

But strange that there is a "Arcade" category where the "Arcade" platform should be instead. I didn't created that category by myself.

But if I move every playlist from the "Arcade" category to the "Arcade" platform everything should be fine again.
