Arena battle points doesn't decrease after I lost my match

I lost 3 matches in a row trying to get an incubator but every time the score remained the same 3552. So does this mean we only can go up till update or is it only me?

Hey Mitul_C_Vaishnav, try rebooting your game and see if your trophy number changes. If it’s still the same, could you contact our support team here at with your support key so our team can take a look at your account?
