Delta V operate face plate Problem. Set point Value Propagating one face plate to Other face plate.DeltaV 12.3

Hello everybody,I am facing a problem related to simple PID loop.

I have two PID controllers FIC and LIC, both are independent and in different units.In auto mode when, I change the the set point of LIC on faceplate (let say sp=15) it automatically
changes the set point of FIC (sp=15).This problem get resovled for sometime by closing and reopening the HMI but occurs again after some time.This set point value is being propagated to
one faceplate to other,I also run the update popup utility and update main picture but not much luck..I am using PCSD Library

A quick response would be highly appreciated !!.

BR

    Thanks every body, problem was due to temp files and yellow pages(errors), solved by restoring the workstations and removing the yellow pages errors by updating the graphic ifix by proplus.
