No, I don't limit the size of the display of results. I just checked; one of your mods is under the user "Tallon" only, so if you filter on War3zuk/Tallon, then you won't see another one ( Tallon's Modedd Extras ). If you look under Installed Modlets, do you have one available?
The screen is awkwardly split between Installed vs not Installed modlets, to help people see what's available and what they have. The Available list does not list the mods you already have installed; perhaps that's a design mistake on my part.
