Hi Petar,
The way catalog extractor works is it assigns the webservice/catalog id used for extraction (dummy id in your case) to field called intcatalogname, later during search the catalog id(2 MDM catalog in your case) defined in organisation plan is used for filtering the result by matching with intcatalogname value.
I would suggest you to have a quick check by validating the value in /SRMNXP/CAT_ITM table. The intcatalogname field value should match with organization plan catalog id.
Cheers,
