LTS problem, provider train stop issue.

[zaratoostra]

Hi

I set a LTS between two block, and when block B is asking from the block A items, the provider station is uploading unrequested items.
please see the following example, the LTS sent a train with a request for single cylinder engine - as can be seen in the train schedule in the first image, but in the second image of the logistic network reading the second image of the provider station there is a request for 2 units of red circuits.
This contaminates the transfer, why is it Happening?
