Routing/Sit down issue on several interactions

My sim and one of her sons were sitting at the dinner table next to each other eating so I clicked on her son to start a conversation with him (ask about day) and when in dropped down into her actions she got up out of her chair with her plate did the tuck the chair back under the table animation like she was going to leave with the plate then put the plate back down on the table, pulled the exact same chair out that she was sitting on previously sat down and then started the conversation with him and carried on eating. I'm on PlayStation so can't share my save unfortunately.
