Default MDR10R Headset not being detected correctly

Hey All,

I have pair of Sony MDR10R headphones (with mic and remote) that I have been using with a Z1s and Z for several months. Since I have gotten my Z2 I am noticing that the device is being detected as a headphone only device and as a result the mic and remote button do not work. The behavior is inconsistent, but about 90% of the time it is detecting it as headphone only.

Most other headsets with Mic work fine and detect correctly except for these. I have tried a couple different pairs of Sony headphones with remotes and see the same type of inconsistent behavior. As a result I never know how the unit is going to function when I plug in the headphones. I'm just not sure as result if this is a software issue or a problem with the headphone port.

Has anybody seen any similar behavior ?

Below are some screen shots of what I see in the notification tray:
