epic games game advancement issue

I just got this through Epic games and got through the first map, the bog ( i believe it's called) and after I complete it, I find that no other maps are available. I'm not sure if I'm doing something incorrectly or if it's a glitch of some sort. I've looked around in the forums a bit and didn't really come across anything about this issue.

Has anyone else had this issue? and if so, how would one go about fixing it?

I've finished the map a few times now, thinking perhaps that if I opened the other garage and got all the watch towers that it would open the next map, but so far nothing.

Problem solved. It was a case of operator error.
