PS5 710 In Multiple / Sehs Free Rome / Issues

Hi, is anyone else having issues when they try to run the 710 emu in multiple sets, they couple up nice and show on the drivers left mfd as 8 cars and 2pantograph symbols show. re-setting the power gives the buzz of operational electrics and the power handle moves freely without any prompts from the game. the power graphic on the left mfd shows movement but nothing fromn the traction packs.
