DRV8312 ignoring reset signal

We are trying to use the DRV8312DDW driver in a design where we need to control the three half bridges separately. Only one of the half bridges is used as a switching node (A) with the other two (B and C) high, low or reset (with adjustments for avoiding BST_UVP when high). The problem is that half bridge B is always active (low/high depending on PWM_B), regardless of the level present at the /RESET_B pin. Half bridge C however works as expected.
