From the screenshot, it looks like the "Hotlink and Element ID" parameter is mapped to the "ObjectID" IFC Property.
You can make these mapping in the IFC Translator Dialog. Click the "..." button in the "Property Mapping" field, then click the "Map IFC Properties for Export" button.
Then find the "ObjectID" IFC Property and change the mapping from "Hotlink and Element ID" to "Element ID", which will not include the Master ID of the Hotlink.
