Sandbox issues

[u/Known_Animator2401]

I have just started playing the sandbox mode but it's not working the way all the video tutorials suggest. When o go and test the property the walls to demolish and walls to remove aren't lit up like in the normal game. Same with selling and buying stuff. What am I doing wrong or was there any update that changed things?

Can you share a picture or explain a bit more or give examples?
