Can we connect EPAD to -15V for ADG1419

Datasheet says EPAD should be connected to -VS substrate. Our application has -15V as VS & we have connected the EPAD to -15V as per the datasheet info.

But now we are observing a weak pull down to VS. For example, even if the switch input (SA) is 3V and when the switch is turned ON, slowly we are seeing the input signal going towards -15V. 

Hence confirm whether EPAD can be connected to -15V, if -15V is VS.
