Amnon, I suspect your problem is due to one of 2 things: either the CATProduct is not the original assembly you used when you first made the External Reference links, or you're trying to add new links to a part instance that is not "in context"
The latest picture you attached shows instances in different contextual states. Thank you for the picture, but you didn't tell me what type of icon your part has?
In my attachment, I've tried to explain what the different icons mean. I hope it's clear.
If what I suspect is correct; activate the contextual instance (green gear) of the slider, and try again to use the surfaces from the mandrel to make your hole. I suspect you may have had an out-of-context (brown gear) instances active, which prevents you from making new External Reference links.
Once you have the green gear part active, also use EDIT + LINKS to check the status of your External References
