Sometimes Cheats downloaded from Gbatemp don't work

well i notice that when i downloaded the cheat file and the updated to the next one the working on the other one don't appear on the new one it got annoying so i started doing it manually again

Please structure your sentence so that it makes more sense please.

Are you downloading your cheat files from the same source every time? Also, which cheat database are you using.

You aren't supposed to use more than one cheat database at a time, make sure you only have one. Please try to be more clear.
