Bayesopt: min observed objective not decreasing

I am optimizing the parameters of a neural network using bayesopt in Matlab. Interestingly, the min observed objective sometimes jumps up which is counterintuitive since I expect that number to be non-increasing. Would appreciate any insights on this. By the way, I used a coupled constraint model: whenever the constraint is not satisfied the objective function will return an error. I also as 'IsObjectiveDeterministic' to true. Thanks!
