Why do I get error message when I change IO termination value with UniPHY memory controller ?

Environment

BUILT IN - ARTICLE INTRO SECOND COMPONENT
Description

UniPHY based IP has only one OCT controller block, thus changing the OCT termination value from 50 Ohm to 25 Ohm for a specific signal will generate the following error message:

Error (174043): I/O "pin_name" is driven by on-chip termination control block "{hierarchy_path}:uoct_control|sd1a_0" but has a termination value which conflicts with other I/Os driven by that control block.
