Zwave Fan control is slow

GE Enbrighten fan control issue. I just installed two new Ge zwave fan control switches and found that even when set to 100 percent, they are slower than the original basic paddle switches. Whats even stranger is that older Ge fan controllers worked at faster speeds as well on the same fan in a different room. I am very confused by how that can be.

What am I missing? I tried the leviaton zwave fan controller and see the same results. I did check to make sure that the fan pull chain was pulled a few times to the heighest setting. Help please!
