Traffic Tool In .17 not spawning cars

After updating to .17 and trying to use the new tool it does not spawn any cars on the map. Help would be appreciated.

 

The Spawn option there is no start button.

 

I have this problem to I press the spawn traffic or traffic with police but nothing happens

 

If I understand correctly, BeamNG automatically detects how many vehicles it should spawn depending on your system. I'm not sure but to me it looks like it thinks that your system isn't powerful enough to spawn even 1 vehicle or maybe there is an bug.
If I'm right this might help you:
Go to Options > Gameplay and set the "Amount of traffic vehicles" to an number instead of "Auto".

 

The amount of cars are definitely not the problem my system can easily take 15 cars when I used the traffic mod before the update so it must be a bug I think but i will try your tip with the settings... Thank you for your reaction

 

Yeah I can’t spawn cars either using the new traffic tool, or police cars. My pc is more than powerful enough to handle 20 cars or more

 

Here with the same problem, sent @Gamergull the files. Will post if I find a fix.

For anybody having this problem, it seems that one or more of your mods may be causing it. Try safe mode or disabling your mods. If you find which particular mod causes traffic to not work, please post it here.
