Can you post the full output from the model?
I am guessing you have an extremely small OR, you could flip the reference group to make it positive. I would also guess you have a very large SE as well, so it seems like there is a huge association which is marginally significant, but when taking into account sampling variability your confidence is much weaker, meaning one of the bounds of the interval is close to 1, the null value for OR. Reasons could include overparameterization of the model with multicollinear terms or perhaps a small sample size.
Though I am just speculating based on the little information provided.
