I used the construction planner to build walls and concrete, but when I ran out of concrete the wall bulding got weird. The robots built some of it, then they just went back. (When I reloaded the map they did the same). I think they are not doing it beause of the missing concrete. I picked up some concrete and everything went normal.

You have so many job orders queued that it takes forever till it reaches any jobs that can actually be performed. Simply don't place tons of BPs of stuff you don't have to avoid that issue.
