One of my performance eval goals is to be essentially cross trained. I was not cross trained how is this my fault? Is this a normal goal?

One of my goals for my 2023 performance evals was to work with 7 different clients. I only worked with 5 clients. The managers are the ones who assign us the work and decide which clients we work with. The managers only assigned me to work with 5 different clients not 7 like the goal states. I guess I could’ve took the initiative and asked for different type of client types but I don’t feel as that’s my responsibility as I don’t assign the work? Does this goal make sense to you? Idk if I’m being stubborn by ignoring this goal haha
