Is it a bug or not ? Ms Project randomly changes project's tasks resources name when re-open file ?

[capsule]

Hi everyone ,



I am experiencing a strange problem with ms project 2016 pro regarding random changes in tasks' resources name every time I reopen project file that I had baseline and closed , I wonder what could be the problem ???

Notes :

I re-install ms project 2016 again just this problem cause by file corruption but no use .

I am having two projects files sharing one single project resource pool file locally ..

I am having problem with the project plan file not the resource pool file .

I know how to connect projects to resource pool

I am also an advance user of ms project ..




Thank you .

Update : After deep troubleshooting , it seemed like i found the case of the problem but not able to solve it , what i found is that in the resource pool file some resources have different calendar , those are the ones who make ms project change the resources of some tasks randomly ever time i reopen the project plan file.On the other hand , the resources which have the project's standard calendar are not being replaced or changed .

My question is : How to make all resources have the same standard calendar , I tried to change those resources' calendar ( who is causing the problem ) but with no success , because once I close the calendar dialogue after setting their calendar to standard the change is not saved .

I am using ms project 2016 pro , I really need your help on this .

Thank you .
