Fields not included in some updates

[Fabrizio Patrício]

We have a stream a stream of trade actions being consumed by a client. In every 3-5 items streamed, there's a field value that is not received.

Is there the possibility of this being connected to the client code? (please see below)

I thought that if I replaced the NonVisualTable mode argument from MERGE to DISTINCT that I would get all fields but I must be missing something.

Any suggestions please? Thanks
