AWS Job is loading with old code

We created a job in aws glue, and did python script code implementation. After our changes we saved the job and it has saved successfully, but upon reloading it is loading with old script which we created initially(initial script). We did changes multiple times, but same is happening. We can notice that some notebook server related error like below:

Notebook couldn't be terminated

There was an issue trying to terminate the notebook server. Please try again or contact support if the problem persists.

Same kind of issue in another job also. What would be the issue here?
