Can you upload your saved game file you are using to test this. I can't replicate the issue. I started the mission from scratch as well as created a quick save before the sams and loaded that and both times it worked fine.
You can find the save games in c:\user\<username>\Documents\Renegade\Client\save
Mission 4: Disable upper sam sites objective cannot be completed
