Mala - "Only Masters" not working ?

[Borderline]

Hey All,

Have done the search and  can't find the answer. There's a similar question in the Mala forum but no response.

1) Have done a fresh install of TinyXP and the latest version of Mala
2) When I Click on the 'options' button top the right of the rom path directory. I select "Only masters" check box, click ok and then nothing happens... game list does not refresh. When I re-enter the options dialogue the checkbox is empty again. It's like the checkbox is doing nothing ?

When you check the other options (only working games etc) the game list refreshes.

3) The same above does not work when you create a custom game list .

Anyway one have any ideas? 
 
Thanks!
