False Positive, Certain and Uncertain Detection Probabilitie

[SBB]

Hello,
I am trying to determine predator occupancy using a single season false detection analysis with site covariates. When I run the model the beta standard errors for <b> are always 10.000000. I read elsewhere on this forum that this could be due to probabilities being close to 0 or 1. But that was in regards to a multiseason model. I have been fixing my <p10> and <b> probabilities to 0 and 1 depending on whether the detections are classified as uncertain or certain. Could this be the root of my problem? Should I not fix these probabilities?
Thanks,
Sarah B.
