Error while resizing clock cells in Cadence Encounter

[biju4u90]

While trying to resize the cells in clock tree using browse clock tree option from clock menu in Cadence Encounter, I get an error like this.

**ERROR: (ENCQTF-4044): Tcl Error in Command 'hierlist_data::updateClockTree clistList ok ctbrowser1@frameOnly_tt ctbrowser1; uiForm::close selectBuffer': can't read "data(resized_node)": no such element in array.

What could be the possible reason?? Can anybody please explain?

Are you sure you have higher/lower drive strength version for that cell

The error is not because of the lack of the cell. I can resize a cell. But if I try to resize the same cell again or if I try to resize another cell, the above error appears even if cells are present. Even I am unable to resize the cell back to the previous cell in use. In short, I am able to resize clock cells for the first time. The error occurs when I resize them for the second time!!
