Bluetooth speaker causing volume increase

[MobileNick]

My wife noticed on her G5 Plus that whenever she turns on her Bluetooth speakers, it cranks the volume on the G5 Plus up to full volume regardless of what setting is there for Media volume. This seems to happen upon pairing with the speakers but didn't happen on her previous phone (Galaxy S5). Is this an Android 7 thing? Any way to stop this from happening?

I searched but all I could find was issues with Bluetooth volume being too *low*
