Issue solved, AliX seller, send to me another RD and I got it yesterday. Connected everything but couldn't connect the shifters. Deleted everything again, and connected first RD then FD, this was working on the app. Then I took both batteries from the shifters out. Pressed the button and added the battery first right. pressed it down and hold the button in. blue pairing light paired. connect to the RD with cable loader on it. Took that off then it's also in pairing mode and Bam connected. Now did the same with the left shifter and connect it to the RD instead of the FD because that's the main connector (the RD) and Bam connected. problem solved!
However, I was too nervous and couldn't wait until the seller and Wheeltop resolved the issue so I also bought another one at
https://xzxcomponents.com/ So in the end I will have two. So if I have got this problem again I have a spare one, this wasn't my initial idea but oke what ever I'm not gone send it back. And Facebook Wheeltop user group was a blessing, what a positive feedback with all the people that have issues.
