relationship reappearing after deleting it reg.

Maybe you are showing baseline relationship lines that have not been deleted yet.

Also make sure the bars as displayed are correct.

But still i can't resolve the issue. Is there any other option?

Normally if we select the activity in the predecessor column box and select remove to delete it, but now its got deleted at that instance but when i reopen the schedule later it reappears again. And i can't understand what causes this happens?

Kindly help me to resolve this.

Can you try copying the schedule on another WBS and making sure there are no baselines defined for this copy.

Do you mean the links are not only displayed at the Gantt Diagram on the right but also keep being listed at the predecessors/successors tabs?

I don't have P6 but cannot believe it can be that erratic, can be bad but not that much.
