Can anyone put a quick light into it. Looked into existing entries but didnt really satisfy with those

I am having an issue in below point of a join stage (warning below)

XML stage ---> Transformer ---> Join stage

In transformer:

Preserver partitioning = clear
In Output tab = Preserve sort order(Enable)
RCP (Enable)

I have 3 such transformers which outout to a join stage

In Join:

Join having implicit sort and Unique enable as well with Hash Partion.

warning:
jontes: When checking operator: Operator of type "APT_JoinSubOperatorNC": will partition despite the
preserve-partitioning flag on the data set on input port 0.
buffer(22): When checking operator: Operator of type "APT_BufferOperator": will partition despite the
preserve-partitioning flag on the data set on input port 0.

Wondering even if the partion clear in upstream still getting warning.

There are two input streams into the join stage, are they both XML-->Transformer-->Join, with hash partitioning and sorting on the join input link and clear partition on the transformer output?
