Signature Fields Disappearing

My current process for getting a document signed is to upload a file in Adobe Sign and assign different signature fields throughout the document before signing. I'm using adobe sign for a few years and never had issues until now.

In the past week or so, when a document has been sent out, the fields that I have inserted have been removed and there is just one global signature at the bottom of the document. 

Also there is always a message saying :There are recipients who need to sign this document that do not have a signature field assigned to them. You can go back and add signature fields or we will add a signature block for those recipients. Do you want to review or send the document? 

Thanks in advance for your help,
