VPIP = PFR but Total AFq is 0. That's not possible?

I'm analyzing some data and I found some strange statistics:

Player A:
17 hands
VPIP of 11.76
PFR of 11.76
Total AFq is 0
( not "-" but literally "0" )

How can this be 0 ?

The formula for AFq says:
(total bet + total raise) / (total bet + total raise + total call + total fold)

Since there is a PFR then total raise should already be more than 0.
I just think there is no way that AFq can ever be 0 in this situation?
Is this bugged?

Total AFq does not include preflop actions, and VPIP & PFR are purely preflop, so these stats are mutually exclusive.

Oh I didn't know this, I thought AFq included preflop actions.

Thank you a lot! This is even better!
