Sitting down next to a table with food and plates causes the table set

[Invctus]

Hello,

 

In a custom home I've been working on I have a dining room table set with silver plates, goblets and food. I put five chairs around the table with (or at least I though) enough space between them and the table to allow the player and NPCs to sit down. However, whenever the player sits (not sure about NPCs; never seen them sit down) all of the table settings go flying, like if you shouted Unrelenting Force at the table. I replaced the chairs with benches that I moved further away from the table and the same thing happens. Does anyone know why this is going on? Is there any fix? Also, is there any way that I can make it so that the platters, food etc. don't get moved by anything? Like some script that disables the in-game physics and makes them static objects? Thank you!
