Duplicate dimension in tuple (rte 381)

I have made some charts in a dashboard that involves two cubes, there are 5 charts/tables which are looking fine and displayable to me.

However, users reply that not all charts/table are working,

for those charts/tables are working, it is using the cube chosen in the dashboard.
for those do not work, it is using another cube in the dashboard. The error message is:

“Duplicate dimension in tuple (rte 381)”

Why the dimension are not duplicate to me but is deemed as duplicate to my users? Thanks
