I’ve had a reply from TR support. I’ll give their suggestion a go but it seems a bit strange to have to do it this way…

Hi there,
Thanks for reaching out to TrainerRoad Support. (:
I did some testing and I think the way around this is to delete the events you have placed in June 2022, and then adding them when you’re actively walking through Plan Builder.
I’m not sure why, but building a plan while including events that are already on your Calendar is breaking Plan Builder.
Try to delete the event and then add it again when you’re walking through Plan Builder.
Let me know how this goes!
Best,
