Response from third party(bank) is not mapping to the response structure

Hello Experts,

I have sync scenario ABAP proxy to HTTP_AAE, I am triggering the scenario from ABAP proxy test tab called "service consumer display" by pasting the req payload there. Request is coming in PI, from PI I have done the java mapping to remove all the ns0, and xml namespace and MTs tags, so its just the actual xml fields without any MT, I mean message types tag.

Bank is also sending response as just the actual XML fields without any extra tags. But the structure which I have created for response contains the MTs and ns0 tags.

Consequently I believe, the repose from bank is not able to map to the response structure created in PI, however the the response which bank is sending I am able to see in SXMB_MONI. But again I do not see any "response message mapping steps " in any of the pipelines trace of SXMB_MONI, even though I have done simply one to one mapping for "response from bank to Proxy response" as my both the structure are same. please see the structure which I have defined in PI and the xml which I am reeving from bank.

Also I believe not all the pipeline processing steps are visible in PI for inbound processing, though I have defined the parameter "TRACE_LEVE" as 3.

Please see the attached screenshot from MONI. moreover the type of main document is "MainDocument ( MainDocument ( application/octet-stream )  ) " , what does it mean?

At last response is not reaching in ECC, rather its remains in PI MONI with "Log version" status, and in ECC its gets times out.

Question

1- Will  repose from bank map with the defined response structure in PI, even if the response from bank is just xml with actual field, whereas PI structure have few extra tags like MTs and ns0?

2- How can I debug whether response message mapping has been called or not during processing, I can see the request message mapping in trace, not the response MM.

3- How to overcome this kind of error, Please suggest.

Response XML from bank in SXMB_MONI -

In the below xml from bank <PaymentInfoResponse> tag can repeat multiple times, so in PI I have defined this tag as 1..unbounded.
