Rubrics not sharing properly

Community Member
As our PLC has been editing assignments that were previously built in our course by our school district and we are using the "share to commons" or share with user function so that only one person needs to type the rubric. However, the rubrics that are created are not transferring after we edit them (the original version gets shared instead). 
We are making the changes before posting to commons but the rubric that shares reverts back to the rubric that was originally built with the class. Then if we try to build an entirely new rubric before sharing to commons, no rubric will get shared. It's like rubrics are not passing back and forth.
Do you know how we can fix this so that we each don't have to recreate the rubric?
