Mighty Rom 2.5 & Sprint Official 6.5 Bluetooth Issue?

[deadwrong03]

Im pretty sure i remember reading about this issue on both of these roms but i was wondering whats the problem? when i have my bluetooth earpiece connected to my phone and a incoming call comes in if i slide to answer the call on the device the audio from the call is coming from the device instead of the earpiece. If i want the call to be answered through the earpiece id have to press the button on the earpiece to answer the call.

on the previous mighty rom 2.1 this never happened and on any other 6.5 rom i tried this never happened either, if i hit slide to answer on the phone and the earpiece was connected, the audio always came through the earpiece. is there a fix for this or anyone know why this happens?
