Definition Update for MSE disappeared from WSUS

Hi,

I don't know what happened, but all the system was working perfectly fine, and today I don't find any trace of MSE updates on WSUS (I'm sure that no more than 2-3 days before the updates for MSE were shown and the PC get them). It's all gone, on Synchronization, needed update everywhere. Does anyone have an explanation for this? Has something to do with windows 10 defender or something. All the domain is with windows 7 and DC 2k8 r2, expect my PC on windows 10 (testing). The product is still selected as seen below. 

 

As seen below no updates are shown
