Bologna-Milano reservation bought but train not visible in railplanner

Hi

Some months ago I bought a train reservation for Bologna to Milano at 11:05 on 14/8 (intercity 604) via the interrail website. However, today I tried to find the train on railplanner and I cannot find it, but I need to add the train to my digital pass… What should I do? Is there another way to find it?

Thanks a lot!!
