The venue is Residential. There are no issues with putting objects on the counter in build mode nor live mode. There is nothing inside the oven.
I appreciate your help. I have tried these before.
Ok. I have thought of one more thing you can try. Try using the point-to-point wall tool to redraw the walls of the kitchen. Just to make sure the game sees the space as one room and has no invisible dividers. If it's something with a floor tile, that should be fixed too. It'll wipe out the wall paint and maybe floor tiles but those are easily replaced. Other than that, I'm out of ideas for you.
Hope this helps.
