I copied an entire course to a new shell. Something I have done for years without issue but this time it generated two copies of my SELF and PEER ASSESSMENT management tools in the COURSE TOOLS area as well as two gradebook columns. The copied assessments will not allow me to alter the submission dates. They remain locked on the settings from the previous course that I imported from and when I try to change them it informs me that the submission dates have already passed. Even if I generate a new COPY of the imported assessments these copies also behave in the same manner.
