partner logo limited?

hi.. i’m saka..
sorry for my bad english..
i wanna ask about partner section..
on configuration menu, i know there is option 5 partner to show, but there is no limitation to how much we insert partners..
For start, i just insert about 15 partner, and their logo show on the partner section in the main page.. all partner logo shown..
and then, i’m insert another partner, totally about 35 partners.. and then.. when i’m refresh the main page, their logo shown there.. but not all 35 partner logo shown.. only 20 logo partner shown there.. and i’m trying to search about this in every configuration, and i’m get nothing about this issued,,

can maskitto’s developer help me to solve this problem??
thanks a lot before..
