In modal position of the v-step is wrong

[as-as2018]

i had provided id as v-step-2 for Choose from our AI Suggestions but it is not positioned at that place but when I'm drag screen window little bit it is positioned.
it is happened in modal only

i'm performing
case 1:
this.toggleSuggestResp()
document.querySelector('.v-step').style.transform = 'translate(427px, 165px)';
break;
but above code will also not work
