[ORD 2021 R1] Container File Temporary Dimensions

For review and submittal purposes I've created container files for all of the categories of references (corridors, terrain, centerlines, ROW, drainage, etc.). I then created a master container which references the individual containers with live nesting turned on. The goal is for this master file to be the main file for reviews. However, temporary dimensions are not working properly in this master file. I am not able to label the slopes of end conditions. The temporary dimension tool basically won't let me pick a start point outside of the pavement subgrade. See screenshot below. Is this just an issue with nested references or is there something else going on? Thanks in advance!
