Hi @LindaK07 ,
It appears you have ran into a defect in the system. I do apologize about this, and I have tracked it on your account. I will be sure to have our engineering team reach back out to you once it is resolved or when there are any updates. In the meantime, here are the steps for the workaround:
"You can rename the series back to its original name by clicking on the pencil icon on the upper left-hand corner of the series management page. Once that has been saved, click on the campaigns tab and the name of the series should now be back to it's desired name. This will only update the series name not the step's name."
Since this defect is still being investigated, it's not a guaranteed, permanent fix, but it may help temporarily.
