The reason it does that is because the FW you have on one of your ROS banks is from a firmware that's newer than the last time PS3 dump Checker's hashlist was updated. You can add the hashlists back into it so that it will work. Ps3pychecker has been updated more recently with FW hashlists, so it found 490 and didn't return any dangers. As stated, it's fine.
