Before anyone can provide guidance - please do share ( if you are comfortable ) :Ppc pics shedul form mariage cfkt etc
1. what proof of marriage did you provide at the time of your application?
2. what documents did they ask for in the ADR?
3. did you provide the same documents in ADR that you provided at the time of your application?
4. Were you able to submit your ADR on time?
If the answer to 3 is yes - then they probably didn't think the original documents were sufficient and were looking for even more documents to see as proof of your relationship. That means that in addition to the documents you already have - please do add further new evidence that you didn't add prior but what that might be is dependent on what you already provided.
