The problem is that WAF expects to see an XML data exchange for any connections going through it, and any XML document will start with the "" tag. What this error is saying is that, what is being transferred is not valid XML. It makes perfect sense if, as you said, the data inside the transfer is encrypted.
In order to use WAF, you need to ensure that the data going through it is not encrypted. I'm not familiar with this Sybase application, but, if it's using SSL, then, the best approach would be performing SSL termination in the first ACE and optionally, SSL initiation on the second one.
