Almost certainly the replacement screen has a damaged home button extension cable. This can be replaced by replacing the backlight (requies soldering 4 pins) or just replacing the 3D Touch panel (which has the home button extension cable integrated to it) which is attached to the metal panelon the back of the backlight. To remove either the backlight or the 3D touch panel you need to heat up the glue around the edges of the LCD. Note that the home button extension cable '''is''' replaceable (it’s replaced every time you replace the screen), the home button and its directly attached cable itself is not (it’s coded to the logic board by Apple).
