Range problems

[DEVIL11 28]

I have had the nelis range and the mercelos proving grounds but I do have problems with both ranges.

1 nelis. When I go to the range I know you are suppose to have more then 1 target but the only target that shows is the runway where you take off from at the base.

2 mercelos proving grounds same thing but the only target that come up is the practice runway and the nuclear power plant i have been messing with both ranges but can't figure out how to get more targets. Any suggestions or help thanks
