Bluestacks Dimensions Emulator

I've been checking my work through companion on bluestacks. This is for my school's semester project. I've been carefully arranging the components' placement to the desired place with bluestack. However, as my groupmates checked on it with their phones, the app was found to be full of misplaced components, incorrectly sized components and such. Is there anyway to correct this or att least a proper emulator except the emulator this site is giving?
