Why there is one vallue of gamma missed on my output?

[karlo]

I'm doing a multiseason (4) model with covars on psi, gamma and p. The individual sites estimates for gamma has all estimations, except for gamma 2 and 3 of site 1. The estimation of gamma 1 of site 1 is there.
exemple:
site survey gamma stan error conf interval
46 70 1 1-1: 0.6117 0.3126 0.1067 - 0.9541
47 71 1 1-1: 0.0328 0.0654 0.0006 - 0.6574
48 72 1 1-1: 0.6063 0.3354 0.0893 - 0.9603
2 2 2 1-2: 0.9631 0.0557 0.5468 - 0.9982
3 3 2 1-2: 0.9336 0.0761 0.5590 - 0.9936
4 4 2 1-2: 0.9821 0.0265 0.7421 - 0.9990
5 5 2 1-2: 0.8730 0.1087 0.5013 - 0.9792

Why the vallue of gamma 3 site 1 is missed?

Program PRESENCE tries to save trees/paper by not printing all estimates. When an estimate is equal to the previously printed estimate, that estimate is not printed. So, gamma for site 2, survey 1 must be equal to gamma for site 48, survey 72.
