Smart playlist with 'Album / Series' is '' (empty string)

Since upgrading to Mezzmo v3.3.1.0, smart playlists that have a rule where 'Album / Series' is '' have stopped displaying any items.

Is this a bug introduced in v3.3.1.0 or a setting change somewhere?

Cheers :)

Hi,
this is a bug that we are working on fixing now.

Hi,
you can download a new Mezzmo installer from our website and run it to repair your installation and this should resolve the problem.

Unfortunately, the problem still exists after carrying out a repair with the latest installer

Thanks for the screenshot. It helps. We have reproduced the problem. You can email us at support [at] conceiva [dot] com for a patch to fix the problem.

I contacted support on 3 Sept and haven't heard anything back from them. Is a fix coming or should I roll back?

Sorry for the delay. We have your email. We are still fixing the problem and will send out a patch early next week to you.

Thanks for the update :)
