NTB0104 unused pins

We are using the NTB0104GU12 device to interface 1.8V logic (VCCA=1.8V) to 3.3V logic (VCCB=3.3V).

On a number of devices, we haven't used all the IOs, so have connected the A side IO to GND but left the B side IO floating.

Will this cause any problems during operation, as I noticed in the notes field in the Datasheet on page 6 that it says:

"[1] The A and B sides of an unused I/O pair must be held in the same state, both at VCCI or both at GND."


Thanks in advance.
