Filter Env release erreor

In the few lessiona back and the one now im working with (nr 5 Brightnes, press and release-Filter Env.Atk'n'Real) In the patch 2 i set Env release to 250ms but i get mistake for that where correct answer shows same settings. I dont know maybe there is shorter time release setinng but in my V2 version of the syntorial i got 0ms and next is 250ms filter Env release setting. So far Its all the patches with the correct answer at 250ms marking it as the wrong. Thx
