error when add one more row dimension in EMP 10.0 add-in

I have created a report which include account, cost center in the row and time in the column, this is a static formt report, I created this by direct input in the cells using the function of activate member recognition since each row has a specific combination between account and cost center, it work very well, now the new requirement is to add the profit center in the row as well, I add a column after cost center and then type the member id which I expected should be recognized by the system, but when I hit enter, the green flash is followed by a red flash and display the error message of "Unable to recognize the report, the initial definition will be applied".

Anybody know how to fix this?
