LM5118: Output slowly rising to 2.7V with no load

Part Number: LM5118

I used the Webench tool to create a LM5118 circuit for 10V-15V input and 12V output at maximal 4A.

The problem is that my output is only 2.7V with no load. The UVLO pin is roughly 2.2V and is never pulled low. It takes about 5 seconds for the output to reach 2.7V after that it stays at 2.7V.

Does anybody have an idea why this is happening?
