Try renaming the label in your script.
For example, if your script says this:
lastName.USERS_DATA_MG as "Last Name",
go into the script and modify it to be slightly different. For example:
lastName.USERS_DATA_MG as "User Last Name",
Make sure you find all of the places that your script references LAST NAME and replace with USER LAST NAME.
Reload the data. Go into your vizs and any viz with "invalid dimension"- update it with the new label.
This should fix the problem.
