Cannot Automate Sustain Below 64 (Need Help)

While recording, I must have hit the sustain pedal once for a short period of time. Now when I play back that part, the sustain holds for about 15 seconds without turning off. I tried automating the sustain, but putting it at 0 in these spots only lowers the automation to 64. How do I go about fixing this?
Pictures shown. Am using yamaha fc4a pedal with P-115, and cubase artist trial.

Open the MIDI part in question in the MIDI Key Editor. Make sure you have MIDI CC# 64 (Sustain Pedal) visible in the bottom controller lane(s):

Got it. Thank you so much!
