Autocomplete not working

[David ..]

Hey :)

I'm having a weird problem with autocomplete, while it shows up as soon as i press tab i get the following scenarios ( i can only explain this with pictures ).

I'm on LIth table version ##0.7.2

and binary version 0.8.4

Before Tab

After pressing tab ( not what i was expecting ).

Or 
Before Tab

After Tab

my keyconfig

 [:editor "alt-shift-w" :editor.watch.unwatch]

 [:editor "cmd-k-b" :workspace.show]

 [:editor "cmd-alt-i" :toggle-console]

 [:editor "shift-cmd-p" :plugin-manager.show]

 [:editor "alt-w" :editor.watch.watch-selection]

 [:editor "cmd-/" :toggle-comment-selection]

 [:editor "cmd-p" :navigate-workspace]

]

What should i do to fix it ? uninstall lighttable is what it comes to mind. don't know.

Thanks,

David
