Anyone had any issues updating a metrel MFT??

I have been asked about a switch unit in a hall which has a switch for the hall and another for an outside light. After changing this switch to a sensor switch everything is working fine apart from when hall light is switched on it switches the bedroom light on as well.
Please can someone help me find a replacement unit as I have been advised wrongly and purchased 8 transformers that I could not return. Any links to the relevant item from TLC, Screwfix, Edmundsons or any other alternative is fully appreciated. Thank you in advance
