Thank you so much! your solution completely fixed the issue. 10/10 would buy you beer in exchange for the advice [quote userid="849891" url="~/products/rail_design/f/openrail-forum/174065/multiple-references-automatically-attached-to-current/552671"]I replaced the active UPF (250 KB) with the stock untitled.upf (3 KB) and the issue has stopped. It's not entirely clear what gets written into the UPF. It may become bloated or corrupt over time especially when running concurrent instances of Microstation that access the same UPF[/quote]
